hi matey,

have a look thru old posts and look for big boost to early.

that was from me , ive got the same problem now, ive just had it set up and it now starts boosting at 2100 revs in stead of 1900, well to early.

doubt it will be a t2 as it would need to be converted to take it so a t3 would cost less so doubt its that, could be a stage 2 turbo and hence it boosting early.

on top of that ive been told theres a smaller equivalent of an ecu for the ignition i think not to sure but if this is messed with it can be set to have it boost early, that and a stage 2 would give u what ive got which is 10-12psi of boost kicking at 2100 and starts to fade off at 3600,

why we bother with old cars i dont know
