Hi
I have been building an ls1 twin turbo for a while and it has been idling/running on a NA tuner locked file, all the way through the build. Long story short I don' t have that tune anymore since its locked and i can't read it, I started with a stock tune. After writing a tune and adjusting injector size up and down and playing with things i shouldn't, i can't get it to run. It fires here and there and sometimes sounds so close but doesn't idle. Is there something in the tune I am missing before I start pulling things part. 3bar SD tune with 650cc injectors. I appreciate any help ls1 turbo 650cc no maf.hpt
