so, the backstory is that I swapped my 92 camaro with a 4L80E/6.0. everything was left alone except for an LS1 intake, E85 injectors (got flow rates off of tune repository and put that in) Long tubes with a short dual 3" exhaust, cold air intake, corvette regulator/filter.
It starts and idles but will pop out the exhaust. LTFT is at 25%
Things that I have done to try to remedy this is a smoke test on the vacuum system, found no leaks
new spark plugs (TR55 NGK gapped at .055) new plug wires, Taylor race wires, swapped injectors for the E85 ones as the truck injectors were clogged. added 25 to the VE Table and now it idles but surges, doesn't backfire anymore though. this is currently what is loaded into the car and a log file.
