Right I've fitted an FPR which for some reason was making my car struggle to start (not every time though) then did some more work on the car this weekend... I fitted an FCD and ever since then it won't start brilliantly when engine is warm (starts fine when cold), I am hoping when I take my car to dyno on Saturday and they set it all up that will sort this but my main problem is since I fitted the FCD it has started making this really strange noise on high boost (kind of sound like a tinny rattle, imagine a stone in a tin can but quieter) lol. Hoping someone had maybe had a similar prob and will be able to point me in right direction? Also this rattle noise was not there before the FCD. Cheers
