87 and Diablo tunes not working

Post by Bates075 »

I received my T2 today, updated it via update agent 1.0 but when I install the tune in my truck, it will install but it basically puts it in limp mode, i press on the pedal and the speedo goes to 120 mph, cuts fuel to anything over an idle and wont shift out of 1st gear.
This happens with both the 87 and the diablo tunes.
I can get it back to the factory tune, but it takes several reboots for it to take.

You have the Trinity T2 EX 9245 Platinum tool?? or the regular Trinity T2 EX 9200??

What's the year, model, engine of your GM vehicle?

Any mods done to it?

What octane gas do you use?

and are you adjusting the tire size when you load the tune?

Please try loading it without the tire size change to see if its ok there.
