Cleaned the contacts and reinstalled. Verified with instructions correct installation. Same problem. Instantly sounds terrible and won't hardly run. I don't know what else to do.

Thanks alot Mike. I will do that here in a few. I've also contacted a buddy in regards to testing the supply side of my fuel pump..just to rule out what I can. I also tried a container of diesel 911 anti-gelling agent. It was 9 degrees when this happened. (Could partially gelled fuel cause this?) I ...

Hey guys,
Used the customer support submission form about 2 weeks ago, and haven't heard back. Figure I'll try here.

I bought an extreme PP as an upgrade to my original. Also upgraded from Predator to Trinity. Long story short..all told. I've used diablosport products for about 60k miles and 5 ...

Thanks Mike. That answers my question. I see it listed there, but I didn't know if there was different ones. I appreciate the reply.

OK, I've read this whole thing...and this computer/techno babble crap still eludes me. Will the RKL tunes work on 7131 or not?

Kudos to yall who can keep track of this stuff...and who understand programming language...I do not..

Thanks

Great Question...I'd like to know as well. I reload the Original Back-Up when it gets cold. That rough idle just makes my soul hurt.

I have used AEM WorkHorse on mine for about 2.5 years and 45,000 miles. No problems, and it will certainly kick up some hell. However I have no numbers for you. So I can't verify it changed anything, but it felt a little better.

ok, I've posted some numbers on DieselPowerMag forums on fuel mileage. I recommend anyone to read that for some information. I have noticed a positive mileage increase with tunes on long trips. My best without it was about 17.5. At the recommendation of my aftermarket dealer TruckAddOns.com retail ...

Ok, I have a similar problem. I'm not sure if this has been visited before or not. I have the r16, never had a different version. My truck Idle's fine, (600 to 800rpm). Now...with ANY tune installed....the idle remains unchanged. However it is cold in Kentucky now, so when the truck automatically ...
