Ive been tinkering around with HP tuners and my truck is currently getting around 13 mpg without driving with a lead foot. Does anybody have a tune file available with the same cam that runs good? I do have access to a stock engine tune that i was planning on starting over with from stock if unable to find one here.
post your tune and a good log and we can have a look to see what you are doing and give guidance on where you should go..Originally Posted by beny5473
I ran one with an 0411 in my Express van. Had a 4L85E behind it. They run good with some tuning, especially with an air intake, headers, high flow cats and decent exhaust. Post your tune file and datalog of a good long drive.

That ran so much smoother than mine. Can you share your tune file?
None of my tune will make much sense if you are still running your stock PCM.
Oh. I'm running a 0411pcm
Your Express runs good with that 350. Just did the same to my '97 Express, L31 cammed 0411, but have not got it to run like yours. New to tuning and just getting out the gate, Lol. Do you have headers? Been looking for some that will fit.Put the marine exhaust manifolds on it but not the same as headers.
Can you post your tune so I can compare it to what I'm struggling with? I can't get my AFR below 18.
