I haven't taken things apart to see what I have but guy I got my 90 model from said they did 1280 kit, stage 7 and removed vboost butterfly. I hear vboost cycle when ignition turned on but no "boost" feel. Does this hurt my performance? Should I fix it? The cyl has a scratches mark in it, he said shop that did bore kit. But not sure if I believe him. Fast but I thought it would be faster with those upgrades
