Good day guys,
I had my truck (details below) dyno tuned a few weeks back and my local tuner changed my IFR from 23.1 to 19.1 on the Engine> Fuel> Injector Flow Rate versus KPA table,... then proceeded to go through a lengthy dyno/street tuning process.
I now know, the IFR was supposed to be 23.1 (instead of 19.1),... my question is; how is this affecting my engine/tune? Am I getting max power with a lower IFR? Will this lower IFR setting damage my engine? Apologies guys, I'm new,... but learning quickly.
Truck details;
1996 GMC K1500 4x4 ext cab
5.7L Vortec swapped to an HT383e/MPFI spider upgrade
Hedman Hustler long tube race headers with dual 2-1/2" ss exhaust
0411 PCM swap from Lextech (with his base tune)
Level 5 4L60e from FLT with Sonnax 3-4 drum upgrade (installing next week)
Rebuilt 3.73 rear axle with Detroit helical locker/Yukon axles and gear
The list goes on,...
Thanks Guys, I appreciate your advice.
