Got Another ?
So after my little test today I decided to install the 93 tune and only modifiy the the "cot" and the "cag's" to see if the lean problem comes back. Im trying to narrow it down to what point in the tune does it make the car go full lean then rich. I am also going to call Mike back tomarrow and let him know my findings.
