my girl has 03 gtp and was told to run seafoam, to clean injectors, better mpg etc... wanted to see any specific way to do this and if it will cause any damage to the car
Run it through the vacuum port going to the lim under your supercharger snout. Dont use the brake booster because it will eat your the coating on your supercharger coating.
GM had crappy ideas?
