I just want to toss this out there so people know, Speed no longer works on LT1 cars. They will do catbacks but thats about it. Trying to get some tune adjustments done because they built most of my car and they turned me away today. Its a shame, they did go work. Now I have to find somewhere else to check and adjust my tune. They sent me to Madtuner, not sure about this place. Anyone know?
