I am running a clean 90-100hp tune and find my truck limping the tranny for a while before the truck gets warmed up. It is not throwing any engine lights or codes. just cuts out and wont let me pass 1800ish RPMs. Any clue what is causing this? I have had trouble with a p0089 code but tweaked...
After putting in a modified CP3 pump in my truck I am throwing a P0088 code high fuel rail pressure! as well as P0089 fuel pressure regulator performance code! I got efi_live I need to know where to go to adjust for the higher pressures.
I am from CA I will setup my signature next I have an 01 LB7 4x4 w/ EFI Live, Straight pipe singal stack, wicked diesel stage 1 CP3, 150 lift pump.
I am in the middle of learning this efi live stuff and registering to forums for help.
