Thank you to everyone who participated in our Black Friday promotion, we really appreciate it! If you have any questions, let us know.

We are taking $50 off our AutoCal tuning, which includes the hardware, custom tune and license, plus we update our tunes for free as long as you own the vehicle.

Just a reminder, save $50 off the AutoCal hardware, tune and license packages. Plus if we are offering deals on performance parts packages. Let us know if you have any questions.

It definitely could have been the fuel quality. Running 87 you would still have pinging going on every mile, even if it is not audible.

Just wanted to add our two cents, the tuner won't even provide an tune for anything less than 91+ for the 6.2, that fuel is required for both optimal economy and best power. 87 octane and, to a lesser extent, 89 octane both cause persistent, detrimental pinging with that engine.

It's that time of the year again! We are happy to announce our Black Friday Sale, for one day only, Friday the 29th! Save big on our AutoCal tuning hardware! Plus package deals available on our performance parts!

Thank you so much for that great review! We are so happy you are enjoying the tune! Let us know if you need anything else.

I wasn't here for the 2009 test, but for the 2016 test GM factory tuning was utilized. I would assume the same for 09. The vehicles are stock for testing as well. That's just for testing purposes, aside from that, a tune can help, some intakes require more tuning than others.

The Airaid Jr (201-796) did the best when we tested intakes in 2009, so it would apply to 07-13 vehicles only. For the 14 and newer vehicles the AFE momentum GT Pro (54-74104)did the best in our 2016 testing.

Thanks Joel! Happy to help!

We should be able to help, if you haven't already, send us a quick email. Thanks

If your AFM is just not functioning properly, and you want that feature, I would take it in to get looked at. You can just disable AFM all together with a tune, which is a really popular change that people make to their vehicles. Technically AFM is a fuel saver for the 14+ vehicles, but people still cant stand it, especially if you have bigger wheels and tires, or can't stand the sound with your exhaust. I have it disabled on my 14 5.3 and have not really noticed a difference fuel economy wise.

We use EFILIve exclusively for tuning, but the compatibility issue might be because of the 17 and newer vehicles enhanced security, 8 and 10 speed transmission lock and so on. We tune with the AutoCal and all you would do is re configure it for the vehicle your going to use it on. Are you able to re configure the diablosport?

Thank you for your purchase! We did receive your files, you will get an email soon confirming that, and that we are adding you to the to do list. Let us know if you have any questions.

We would be happy to help. We are able to to tune some 2019 models. We would need you to email us the VIN and we can check how we can support it. Thanks *I believe the 2019 6.2 we are not able to tune, just the 6.0 and 5.3, but you can still email the VIN, and we can double check.
