SCT Tuner Safe on Engine?
So I just got the SCT Tuner from AM this weekend. I loaded the 87 performance tune and the car ran fine. Yesterday, while I was driving 2 of my spark plugs detonated. Luckily it wasn't too bad. The mechanic said its because they were the wrong brand, Bosch. I now have Motorcrafts in and it runs even better now. I was wondering if the tune had anything to do with it or just sped up the process.... And is it ok to daily drive the performance tune?
