Ok,i read on here all the time about guys getting there 1070 motors tuned on pump gas,my question is,how are you doing it?
I always have to get mine tuned with race gas, pump gas mix and naturally when i run straight pump gas my tune is off and it pings like a son of a bitch down low. All i have is a je 13.5.1 1070 piston kit,with big valve head and cams.
I dont race anymore, so im trying to get it tuned on straight pump gas, got it apart right now,thinking about putting in a thicker head gasket to lower compression.
Any help would be appreciated.
