hmm same problem i had with my fezzy no history didnt know what was done to it apart from the obvious things like it had the t3 conversion, beige injectors but no chip thus overboosting. After learning a lot from these site found out my cars running an OFAB managment.

anyway heres a pic of an OFAC map sensor look in the engine bay on the bulkhead and if it looks like this then ur ecu is an OFAC if not then an OFAB and i doubt that ur running some aftemarket uprated management but if u can get a pic up ppl we'll able to confirm it for you


good luck
