I need your help people, yet again. Does anyone know a reliable tunning shop with a dyno that knows how to use the emanage/profec that can tune our engine? Near Houston, Dallas, San Antonio or Phoenix. I am running way to rich and if I take the car to the same place after I place the S20g I am going to get the same rich AFR.

I don't know why, but they removed the SFMU and replaced it with a FMU! WTF?! The car runs great, but it could be better tuned at lower fuel preassures and not be lean at all. Thank
