Hi Guys,

When i collect my 159 2.4 Ti qtronic this week I'm thinking about getting a dpf & egr delete + remap just for reliability sake. I don't particularly want any more power due to extra loads & stresses on the engine. My local remap specialists told me they use the same map for extra power as they do for economy, he maps the car for fuel efficiency at less than 50% throttle & power for greater. Total cost is 350+vat. Does this make sense? Have the guys that have had remaps experienced any turbo problems with increased boost etc? Also is there a noticeable increase in soot from the exhaust after the dpf delete? Is there anyone on here that has a 2.4 qtronic that could give me approximate mpg figures? My commute consists of approx 10 miles of small single track hilly b roads + 2 miles of A road + 6-7 miles of dual carriageway + 4 miles of standard B road.

I have the 2.4 Ti Qtronic and had this work done by Angel. The result is excellent, loads of power and improved economy. As expected, if you use the power the economy drops significantly, but on long journeys it is considerably better than before the work was carried out. I dont have any figures as i havent bothered to calculate it post map, but the trip is usually around 5-8 mpg better as an average. Given the computers go out after mapping, id imagine the reality to be around 2-4 improvement.

The box even holds gears now as it has the additional torque, where as before it would drop a gear when i'd have preferred it not to.

It does smoke a bit under full throttle, but you have to be looking for it in your rear view mirror and to be honest you will not get 250-260 bhp out of this engine without a DPF and not have smoke. It is not excessive and its behind you so not your problem :D

Hi,

I am considering remap and DPF removal are there any negative side effects on the engine or other parts of the car?

I looked at Angel and for remap, dpf removal and egr disabling for £430, does this sound about right? I recently had my egr valve replaced by the sounds of it I could of by passed this price and had it disabled.

I'm having my 2.4 Qtronic remapped and dpf removed/egr deleted by Angel Tuning on Wednesday.. so reading "Alfa.Romeo's" post is very encouraging as I haven't seen much said by anyone with an auto before and so I did have some hesitation. My commute is only about a ten minute drive on B roads and so the mpg is terrible (as expected) so I'm having the work done more to just let the car "breath" properly and be a bit nippier. A bit of bonus mpg over long runs will be a nice extra but I'll be more happy just having it "feel" better rather than the low end lumpiness it sometimes has. Fingers crossed!

But yes referring back to the OP I've read pages and pages on here about this work and have finally just decided to go for it.. from what I've read it definitely seems like a step in the right direction, and in hindsight I wish I'd have been brave enough to have got it done when I first purchased it rather than leaving it 18 months like I have!

Read the threads there are hundreds.

Your choices tend to reduce to about 4 suppliers. The only fact is that you will NOT get agreement who is best to use but do it - it is amazing!

My 2.4 cars have NEVER given improved economy but we do use the extra power. The trip computer post remap is even more innacurate and shows an untrue improvement of between 4 and 6mpg.

Reports suggest that the 1.9 gives a relaible increase in economy. The 2.4 is now an almost ancient design and if driven moderately quickly will struggle to beat 32 with town driving and 36 with mixed.

Some people report higher figures but they also report tyres lasting close to 40k. Post remap and 4 wheel alignment done my wife gets 31 - 33mpg with 75% town and 25% open roads and wears front tyres in 12 - 15k miles.

EDIT my wife's car is manual and a 210 so older style turbo.

Well worth it, Angel remapped mine a few weeks back, it is a different car immaterial of any mpg gains. as Alfa.Romeo says it chuff's a bit at full throttle and when starting from cold but you would expect that once the filter has been removed. You will be impressed.

I had my 1.9 JTDm remapped a couple weeks back and am really pleased with the results. Much reduced lag under 2000rpm, better economy and it pulls like a train. Only thing I will say is that if you decide to declare it to your insurance company, like I did, then you may have some problems. I couldn't find any of the big insurers who would insure anything over a 30% increase in BHP, which mine was. In the end I've had to go with a modified car specific company and its cost me more. Only about £50 more than I was paying before but still a hassle. It's absolutely ridiculous! If I had bought a stock 400bhp car I'd have got insured no problem, yet just because it taken mine up to 195 with a remap the idiot insurers won't insure it. Now most people will say you don't need to declare it as its undetectable but I wanted to be safe as some people say it is detectable and we all know insurers will look for any reason not to pay out, including not declaring a remap. Having said all this my dad had his A6 remapped with the same percentage gains and Admiral insured him no problem with no rise in his premium, so clearly they're discriminating against me because of my age (26. When do you stop being classified a young driver?) Anyway, that was a bit of a rant. In summary: most people would say don't declare it, but if you want to then be prepared for either a hike in your premium or having to change insurers. End scene

Had mine done at AHM a couple of weeks ago. Completely different car in every respect.
Starting from cold, pulling from cold, economy and best of all it goes like stink.

It's ridiculously good.

I was thinking of the 210 remap. Should I be brave and step it up a bit? What is generally considered to be the best and how high can you safely go without compromising mechanical parts, clutch, turbo, drive-train etc?

Quinnj3, who are you getting to do the remap? I understand that in NI the MOT tester will fail your car if it does not have a DPF (if it was originaly supplied with one). How do you/your remap specialist intend to deal with this issue?

Mclennans in Edinburgh, phone and discuss it with Stuart.

He works with Gus at Alfatune, so its probably the best developed map.

I have a few technical question now you guys may be bale to help:

Remap only - Actual/common performance increase at low revs, MPG, motorway cruisng?
Can you have a remap and EGR valve deleted without removing the DPF?
Why do you need a DPF if you can remove it and still pass a MOT?
Know/common side affects of a remap?
EGR valve delete do they actually remove it?


If you copy and paste those question and write your reply under each question that would the most clear.

NJS remapped my 2.4 Q-tronic and removed the DPF. The remap for the auto results in about 240bhp rather than 260 or so for the manual. This is not to preserve the gearbox which is plenty strong enough but to give the right torque characteristics. The result is a much smoother power delivery and about a 7mpg improvement.
Neil replaced the DPF with a straight pipe and I have kept the DPF in case of future MOT problems, or if a future buyer wants to install it.
The cost was about £500 but Neil's argument was that as well as all the performance advantages, I would avoid the inevitable £1500 bill for cleaning out or replacing the inlet manifold.
So far there have been absolutely no disadvantages in having the work done.

As far as I am aware there is no legislation in the UK that requires a diesel vehicle to have a DPF fitted. Therefore, it can be removed without penalty (MOT fail) There may be a requirement in the future but it will only apply to cars, vans etc manufactured after the legislation is passed, it can not be retrospective!

Hi Guys,

Thanks for the replies. Does anyone know where the best place in Northern Ireland is to get a remap etc? I've heard of Torquetronics is there anywhere else?

Thanks for the help Guys, I spoke to Nigel (I think that is his name) at Angel Tuning and he was very reasurring claiming 13% to 15% improved ful consumption.

I did some maths based upon my current mpg: 32, current diesel costs: 140.9p per litre, price he quoted me: £330 all in (full remap dpf/egr deletion), filling up approx 2 times a month, 10% better comsuption.

I would save £255.6 a year in fuel and I plan to keen my car for 2 or more so years yet (2007 reg.), that works out that I will be up £211.2 over two years which should pay for the difference in my car insurance. Plus reducing the need to ever replace the edf valve (gutted, did this jut 4 weeks ago cost me £200) and dpf (approx. £1000 to £1500, around 100,000 to 150,000 miles) and if you want to get particular you save weight too. I have a Spider, don't let those sexy lines fool you, it is a real fatty boom boom (Over 1600kg).

I would say I was airing on the side of caution and if I went with Angel tunning recommended comsuption increase (13%) I would be looking over £320 approx. (third more) saving a year (presuming I drive as I do now, occussion foot to the floor).

To me it is a no brainer in a way, hope this helps. I am hopefully going to get this done ASAP if I can afford it because I have car insurance due too! For me I think I'll be breaking even over the time I plan to keep the car (maybe up) with more performance with less things to worry about!!
