It Does Not Do This When Changed to Stock. Only on Tunes.

I am making sure that i remove all electronics while applying tune and get no errors.

I have tried changing many parameters.

I am at the Point where i am considering not using the tune.

I get significant bucking only at a hot engine ...

Hey my i3 platinum also has no option to click should I assume disabled? And what does it do?

the Diablo Tune (the 91/93 octane tune), has higher timing settings than stock, meant for the higher octane gas... timing is set higher than the 87 tune...

The 87 octane tune uses mostly stock timing settings, it's just bumped up a little in the lower rpm's in the WOT area...



Ok it doesn't do ...

if it's very intermittent, doesn't do it every time, only once in a great while.. then it's not tune related... if it was the tune causing it, it would do it all the time, every time...

so, since it's not, then that points to an issue with your truck itself... not the tune...
Ok thank you for ...

Not sure.... good idea. I will check right now but it is so intermittent it's hard to get it to do it. Happened when I had diablo tune (91octane no ethanol) and timing solved it not in this case though. I'm cleaning my throttle body to rule out as well.

As it States my 2001 chevy silverado 2500hd 6.0 la particularly on hills sputters and hesitates before stalling. Particularly uphill. But if I retune the vehicle it starts again. Do I need to add fuel increases? I plow so major problem. 87 octane tune.

Beuler... now having speedo issues

So I tried entering wheel size after the speedometer was half speed from changing my axle ratio. Only problem is it won't save and when it say saved it makes the vehicle throttle on and off kind of bucking. Please help. Also any input on parameters to modify for plowing.

I have no clue where to go after changing my idle and changing the gear ratio.

Hopefully some of you guys can help me just bought an intunei3

The platinum version. And I bought it to really change the idle speed for my alternator but I want to use ...
