I think the factory ECU is crap. The performance of my car varies pretty much from day to day and I don't know what can influence it so much. sometimes it drives like a 1.4l engine not a 3.5 and it revs very hard and sometimes I'm amazed how well it accelerates and shifts (auto)

maybe I'm paranoid but the performance varies too much. It's like driving on a hot day or in a cold clear morning

i said the samething today , except f**ken ecu is f**ken chit...
yesterday was good, today lagged somethin stupid hot breeze i'm hoping it was for mine...
