Stuttering problem

[SkylerJayy]

Mods : LS1 with Torquer V4 cam, 243 heads, fast 92, Chris Johnson twin 450 fuel pump, deca 80# injectors, Huron Speed V3 Single turbo kit... much more to list

I had been getting tuned over time by the same person with no issues at all, no complaints.. I had a exhaust on the car that was restricting the turbo and causing a stutter under minor acceleration.. the exhaust was removed but the stutter was still there but was much less. I really couldnt see it in a log so im going to post it here hoping maybe someone can help me out on this one. Ive seen no leaks or etc..r1.hpl

forgot to mention, this isnt a finished tune.. i upped the boosted and swapped clutches so ive barely begun getting it tuned again

Post the tune.

There are a lot of issues with fueling going on. It's either like 20-30% lean or it's 30-40% rich based on the short term fuel trims. Has some massively wild swings in fueling. And if those are truely 80lb/hr injectors there should be no reason that you are going past 100% duty cycle on only 10 pounds of boost.

I have a feeling the injector data is way off and likely your fuel pressure too. Is your regulator set to 58psi??
