That was my thoughts. Having fueling issues but never give a injector part number. Could be the 19lb 99 injectors for all we know. Probably just the standard 25lb set. The file looks like a generic swap tune from a harness supplier.Quote:

Here is more details
Engine was pulled from a 2005 Tahoe the full motor with everything on it and the ECM went right into the car I had to get a oil pan and headers so that changed the intake tube wouldn't fit so the MAF is mounted right in front of the intake itself.
So all the injector data and everything in that file was stock to the ECM, The stock file is the file I posted "G35 First Scan"
Could you still verify part number? Fuel regulator?
05 VIN Z is going to have an in tank regulator with a returnless rail in the stock donor vehicle. If everything was moved over it won't have a regulator on the fuel rail.
Yes it is a returnless set up and I put a adjustable regulator at the tank and ran a return from that back to the tank. so fuel rail only has a supply line.
I have checked my fuel pressure at the rails at idle still haven't checked under a load, 58psi at idle.
Are you sure you have 58 psi fuel pressure? Reason I ask is most Nissan products run at 51 psi. The regulator is internal to the fuel pump and they are returnless. What year is the G35?
That being said it is entirely possible for headers and full exhaust to require that much more fuel. The engines VE increases a lot when it can breathe.
Honestly.. kinda pointless to carry on without checking.Quote:
