Before I buy a Predator, one question

[TexasTruckin]

Just bought a new '09 Silverado 1500 5.3L (FlexFuel w/AFM) 4x4 Z71.
(FYI: I avoid E85 it at all possible)

It is currently bone stock. I'd like to buy a U7194 and run one of the preprogrammed tunes until I add a CAI and backcat, then I'd have a custom tune done for me.

The one thing worrying me is warranty work. If I had to have dealership work done I'd reinstall the stock vehicle tune beforehand but will the dealer be able to see my previous Diablo tune?
I found a thread in the GM Diesel forum saying the dealer wouldn't be able to see it but I wanted to double check that it applied to all Diablo tuners.

Thanks!

as long as you restore the original backup stock tune back to the truck before you brought it in for any service work, no - the dealers can not tell that it was ever tuned or that anything was ever changed...

Excellent! Thank you for your quick reply. I'll be picking one up in a couple of weeks.

also, you'll want to get the PC interface kit so that you can connect it to your PC to update it to newer revisions if need be, to download saved/recorded data logs, and to import/export tune files for when you want to get a custom tune made....

you can get either a serial-to-serial kit, or a serial-to-usb kit... they're listed on that same page as well...
