Exactly my point with a lot of things. Just buy the one that has been manufactured to actually go that quick and handle that power all day long.
Sure if you like tuning etc then go mad.
I guess with a lot of diesels people get them due to mileages and then think of its quite easy to get more power for a few hundred. Which is a good way of thinking. OEM+ a little bit.
But those who want 250hp from an engine originally with 150 - 170 must know you'll be pushing limits.
Still I'd look at a different map. As it seems like you've tried to fix one problem after the next and made the car usability worse.
its a good point, to a point.
i have heard as many horror stories about the 3.2 V6 as the derv and they share exactly the same suspension components, which are going to be a big part of the outlay in maintenance on a daily driver.
if you get a derv correctly and sensibly fettled and mapped it will give ongoing savings that are palpable in the pocket on a weekly basis as well as blistering performance, I have driven a 3.2 and have to say my mapped, and suspension modified derv gives the 3.2 a very good run for its money in every way but the sound it makes.
I cover 650 miles a week, it takes one tank to do it...I suspect on a 3.2 it would be close to double that, even with cheap petrol at the mo i'm saving around £200 a month..
that means in a year I will have ''reclaimed'' my mod spend and can do all routine servicing myself in the future.
Of the money I have spent on my car only the map and EGR delete were diesel specific work. There is no guarantee I would not have had to have done all the other work on a 3.2 had I purchased one, with no chance of ever evening out the investment over a period in fuel savings.
so you pays your money and makes your choice, each to his own.
