    i replaced tps 2 months ago cause the light came on and it was messsed up and i dont have the stock coils they were fried also i phoned 3800 performance who specializes in these cars and told me you dont need to tune the comp for higher compression as they do top swaps on the 3.8 n/a all the time and use the gtp engine tables for the ecu and they are 9.5:1 compression hes also the guy who sold me all the parts one thing that is bugging me is when i pulled the vacum line off that goes to the fuel rail it was full of oil after i blew it up and i blew it out with compressed air wen i was reassembling the motor im wondering if i damaged the fuel pressure valve at all its at a shop right now and they are scanning it it seems to hunt alot wen its at an idle once its warmed up as well

    The L67 engine is 8.5:1....you didn't come out and say that you were using an L36 bottom, but I assumed you were (b/c of the pistons you mentioned). So if "they" loaded L67 tables...that doesn't make sense to me.

    As for the FPV - I don't have an answer for that question. Sorry.
