I just put a turbo and changed the entire fuel system on 00 ls1 has cam stock heads and intake with 80mm turbo and 210lb injectors with 2 450 pumps on cold start it will run around 10.5-11.0 and sputter all the way till im almost at work then boom just switches over and runs 13-14 afr I only run the 2 front o2 sensors
tune Is far from final im still dialing in the VE and smoothing but cant seem to find anything like this
at the end of the log you can see it jump from 10.5 to 13ish AFR then I stop the log so I can see if theres any changes. its speed density tune no MAF
if anything looks a little funky in the tune let me know all help is needed lol
