73,000 clocked up now & no problems so I'd say spot on to Shauncorwyn...
Sharkrider has clocked over 100k miles too, its not the re-mapping that causes the problem, if anything its how the car is abused and / or neglected at certain times in its life, whether due to ignorance or plain neglect.
I serviced early, 15k miles instead of 18k. Insisted on the correct oil type & grade, and ALWAYS took care of the engine & turbo when cold or hot. Still schweet... for the next owner :yum:
indeed, mine was mapped at 4k (by angel though, not reddot) and I'm now over 100k without problems,recently went to RR session, and still giving the same power, no drop off in performance, mine does however whistle, always has, my fiat tech says its not a problem, says he has replaced turbos on whistling cars only to have the new one whistle anyway.... so I'm not in the least bit concerned.
Other cars do this too. most notably the PD140 VAG engines, a friend of mine has an octy II PD140 (mapped to 180bhp) which whistles like mine, and he has done over 80k and its still going strong.
If you can get it replaced under warrenty , fine, why not? if you are out of warrenty (like me!) I wouldn't worry about it, mine is still going strong...
as someone else said though (depending on the mapper) boost levels are only increased a very small ammount on these engines,if at all, the rest is done with fuelling, so a map shouldn't ruin the life of your turbo.
I never boot it from cold, and always let it "cool" with a gentle last mile or so before switching off... (also stuck to fiat 18k service intervals, of course using the correct selina oil, this may be very important (the oil) ,I know the VAG engines die if the specific oil isn't used. I have also never had to top up the oil in the 100,350 miles I have done!) this is my philosophy for a long life for your turbo.
