I just installed a turbo on my 2013 LS3 Camaro. I had tuned for partial throttle first and my fuel trims got down to 0.0 and my afr was good for idle. Today I turned my car on and it started to surge in low RPM. Once I got to a red light and put the car in neutral it leaned out and almost shut off on me. However, under throttle, everything had been going well and has no problems keeping the AFR in the 14s while driving. Let me know what I can alter b/c I'm pretty sure it has to be in the tune. Car is completely stock besides the turbo. I have fuel injectors and a pump I'm going to install when I up the boost. I am pretty new to this so thank you for your help!
