[QUOTE="2001Bullitt, post: 16668573, member: 100458"] Sounds exactly like the issue I’m chasing as well with my Turbocharged Bullitt. Thing was a beast for like 2 years after I built the motor in 2015 and had it at 14psi, 509/518 numbers. After about 2 years it started breaking up just like yours, cutting out and backfiring. I recently installed twin 340s and a return system, new 80lb injectors, oem cam and crank sensors, oem coils, new TR6 gapped at .028 (per my very reputable local tuner). Retuned it at 15.6psi and it made 604/626. Did pop a few times after he let off on the dyno, but then after some tweaking it was fine. But it’s still doing the same thing on the street lol… driving me nuts just as I assume yours is. He told me I may need to check the reluctor ring behind the timing cover to see if the keyway is worn out, it’s the only thing I reused during the engine build.. im lost as well and about to just give up hope and let it rot in the driveway [/QUOTE]
