So my tuner is STILL junk. I've called, tuner was updated, no I dont have any aftermarket things, emailed everyone I was told to email (with no response) , I've done EVERYTHING and still I'm stuck with a dangerous tune in my truck. Plug the tuner in my vehicle which is on Diablos highest canned tune ...

My 8.1l 1-2 is extremely laggy if I'm not gunning it. Have you noticed that when you punch it, the vehicle keeps accelerating on it's own?

So tech just reset the device apparently. I did an update as suggested. I plug it into the vehicle and I STILL have the same problems. What really sucks is you have the same business hours 90% of America has so its REAL difficult to try and get home to call your tech.

Ok...

...

Will I lose my custom tunes?

...

I have, no better results.

Yes the Diablo tube is loaded. I want to put my custom tune back in and also read my CEL. Stock stereo.

….

So when I try to use the scan tool, I get "an unexpected failure has occured" then it creates a failure log. On the tuning side, when I hit advance tune it just freezes.

It worked fine last week, now it wont work. I've done everything you suggested.

Im trying to use the scan tool option, says failure occurred and then failure reported. I try to put in my custom tune and the handheld freezes when I press advance tune... all updates have been done, very upsetting to spend so much on a device that has so many issues.

You can have Diablew make a custom tune for you....
