I am the first UK owner of this car and it has always had a FCD from when i bought it, I have not got involved with the fueling on the car, nore have i had it dyno'd il be honnest. But when I found out about the Jam FCD, i noticed the ECU looked to have been played with, and also had stickers on at one point (sounds silly), so at the time i thought possibly an aftermarket ECU was installed on the car but i cannot comfirm this nore did i mention it in my first post.
Liam - I dont understand what your saying, why shouldnt the car spike with the mods stated?
