Thumbs Up A few tuning questions etc.

Following my thread in the introductions area I thought I'd post a thread in here.

Okay I'm considering getting a 147 or GT JTDm 16v and doing a few mods.

Remap - where is best? Celtic tuning seem to promise the highest gains.

Exhaust - is it thought to be worth fitting a complete exhaust (from the turbo back, removing the cat in the process). Are some companies better than others - Powerflow vs/ Longlife etc?

Air filter - is a panel filter thought to be the best bet? I have a massive cone filter on my Rover which means the turbo sound sounds great, but I'm not convinced that it does a massive amount for performance.

Turbo upgrades - is there anything bolt-on available?

Drivetrain - firstly the clutch - from reading around the forum it seems like I will need an uprated clutch following a remap - one of CG motorsport's fast road ones seems to be popular?
Flywheel - is the standard DMF up to a remap when renewed? It seems that it would be better to replace it with a single-mass replacement, but some on here seem to think that doing that is risky?
Diff - is the diff at risk of blowing up after a remap? I am aware that some fit the Q2 one, but I believe that that is because it is a LSD?
Driveshafts - I've heard that they can be a bit fragile? Is it just that the CV joints wear and knock or something more serious?

I would be aiming for 200 maybe 220 hp.

My first port of call for a re map would be Alfatune in St Helens, forget about the highest gains in bhp you want a map that delivers the power how and when you want it, Gus will give you the performace you want and will adjust his maps to suit what you want within reason.

Alfatune also do custom exhaust work and can advise on clutch and diff modifications.

Have a chat with Gus before you do anything, he's not a bul****ter and won't sell you something that you don't need or doesn't give the gains he's promised.

+1 for all the above. Mines had the full F1 remap with DPF and EGR deleat, full exhaust and decat all from Alfatune.

Gus is the man. His remap delivers the power in such a smooth linear way it make the car awsome.

Thanks for the replies!

Sounds like Alfatune is the place to go.

What's the general concensus on FMICs?

Are the standard ones good enough for 200 hp or so or is an upgrade required?

What sort of power could I expect with a remap, decat and full exhaust system?

Thanks in advance.

various Alfas

The power depends on the year of the car as well,a later one (2007 on )will achieve more easier,also depends if you start with a 150 or a 170 bhp one.
With these in mind,get your car first and give us a call

Ideal - thanks.

Will probably be getting a 2005/2006 150 hp one I think as can't quite stretch to a post 2007 or 170 hp one.

Might well give you a shout when I get one.
