Just wondering if there are additional tunes available besides just the 87 octane one that I already have?

I have the I1000 and am tuning a 2015 GMC Sierra SLE with the 5.3L.

Thanks!

It works!!!!!

I feel like an idiot but it works!!

Didn’t give it enough time when updating it on my PC.

Feel a big difference already, and that’s just the basic, I haven’t even touched any of the other options yet.

Thanks again for all ur help!

So I was able to update the unit, but when it goes to export the original backup it says erro exporting unknown pcm.

I double checked the application chart and it says my truck is supported.

So there must be a way to get this damn thing to work!

What’s next??

Tell me more about this upgrade to the I3!!!!

how do i go about doing that??

Thanks!

Will try the ignition program tonight when I get home. But when I looked for updated software for the i1000 I could find anything called ignition. Would it be located somewhere else?

Thanks for the quick reply!
