Hi
Can deffo say that Racelogic TC dont work if you want it to make your car go quicker. It will stop fish tailing in the wet at the expence of it making your engine sound as if its f**ked. I took mine off after about six months waiting for it to perform miracles. Mark Shead had a Technical Term for it " Totally Shite".
However its part of the Autronics ECU package on my new engine so will probably have another fiddle.
