Thanks for the suggestions... might be a stupid question, but does this eliminate the need for the stock fuel filter? It's a pain in the ass replacing that filter and my inner fender has seen better days.
I should also note that I don't run that tune towing heavy... honestly have only ran that time a dozen or so times since I've had it.
I know resetting the DTC isn't going to fix the problem... hence why I'm in here getting advice.
I'll look into a lift pump and check my fuel lines. I've read...
No lift pump and fuel filter is probably about due for replacement.
Pardon my ignorance, but what's a bottle test?
I don't run that tune often since this started happening.
Im not a big tuner guy just want the power when I ask for it.
I have an 08' that I pulled the emissions out of. DPF/EGR deleted. PCV bypass, CAI, and a 4" exhaust with a muffler to quiet it down. Also have an H&S mini maxx tuner. The tuner has 4 power settings that you can switch on the fly...
