Piston is dead...pics soon. Cyl walls look OK. Plan on honing, new piston/ring combo and then back to square 1 with tuning, being very careful this time. 10 psi max til we get it right. might go back to maf tune. getting opinions either way it's a toss-up. looking into more fuel to rear cylinders to avoid the detonation in #7,8. Can HP Tuners adjust inj pulse width on indiv injectors? Allen?
Goin to machine shop tomorrow (not wasting any time). Overnighting parts asap.
THEREFORE, turbo not for sale (sorry cuz) YET. Will keep posted.
Anyways, the trucks need to be represented around here. Too much rice and crustangs.
