I just started autocrossing......after several events, I am not at the top but I am certainly getting somewhat competetive. I am looking to do some engine mods this spring. I am looking for increased performance in the low RPM range
With STX class, you can modify the ECU but you can't change boost levels. Does anyone know who offers chip mods that don;t alter boost. Cobb tuning tuning has an STX map but it requires a new downpipe. I don't want to add the downpipe but I will if that is my only option.....
Any advice would be appreciated.....
