any idea's ! diablo preadator u7198 question?

[payne]

i just got the diablosport u7198 for my 99' silverado z-71 5.3L and it took the factory program out and saved to programmer, but would only let me put in factory hp tune. i tried to change the tire size and other settings and it said it wasn't available for the engine and transmission combonation. i'm pretty sure the performance tune is working because i notice more power at low rpm and 4000rpm and higher. i have been running 93 octane ever since i programmed it. does factory hp tune mean that the performance tune is in my ECM or is the programmer not working at all ? i checked my vin code and it's " t " just like the model # say's it will work for. can anyone help! thanks!

factory hp tune is just a copy of your original stock GM tune... it is not one of the performance tunes...

at the main menu, if you go into Performance Tune - you didn't have choices for Diablo Tune or 87 Octane Tune???

what revision is that predator on? when it's at the main menu, the revision number is at the top of the screen...

it never gave me a option for 87 octane. it said performance tune, change stock settings and diagnostics. it would go into the performance tune area, but would not let me change anything else. it said that it was not available for this application. i was able to go into manual or automatic trans selection and that was it. when i went into change factory hp tune it was downloading something. i'm not sure about the revision number, how can i tell by that number? i thought that it automatically changed the settings on the fuel,air and trans settings on performance tune. i will get that revision number soon! i have to hook it up again.

when the tool is powered up and at the main menu, the revision number is at the top of the screen...
