Learning my car failed the MOT, visit thread please if you have any ideas on major high emission fixes/tests I had a chat to one of the guys there.. He was saying that if uprated the power etc in my car, in the end I would have to have a mapping for performance, and then a second mapping just for MOT tests..
Is this really true? Anyone had to do this.. Oh and he slagged off forums then advised me to think about twin turbos for an upgrade, not a single, as they are too much power at once for a road/street car..
On a scale of 1 to 10.. How much is this guy shoveling?
Need to know, as he wants me car back on Wednesday to test this running rich problem and emissions stuff, so I would like to try and find the problem myself, without him getting his hands on it again if he sounds full of it.
