2008 GT500 - Return Fuel, FIC 1000
2008 GT500
Just changed to return fuel system. Fore hat, 2 hellcat pumps, -8 feed & return. Car was tuned with HP previously, stock pumps & injectors - ran fine.
FIC 1000
93 octane
JLT 127
Trinity Blower
FPR @ 55 with no vacuum. Haven't been able to get it out of the shop yet but having an odd issue with going extremely lean at tip-in free revving (20-25%). Planning to log it tomorrow. Will clear up as MAF voltage settles. Can hold constant RPM fine with reasonable STFT. MAF transfer unchanged from tune prior. I know injector values have been input correctly according to FIC data. Can someone take a look at this to see if I am missing something obvious?

It just needed more fuel. Imagine that!
