For those of you who do not know us, please take the time to check out our website, and see some of the products we offer for late model GM vehicles.
DiabloSport's Website! (http://www.diablosport.com/index.php)

We offer handheld tuning devices for a wide range of GM (and Ford and Chrysler) vehicles from Vettes to Escalades, Camaros to Duramax diesels, and more.

The tunes in the Predator or Trinity devices offer increased performance, fuel economy and fun factor. Throttle response is improved, and your GM vehicle will run like you knew it should have from the factory.

The tuners save a copy of your stock tune before it loads a performance tune, so if you ever have to go back to the dealer, for any reason, you can simply restore the factory tune back to the PCM, and there is no trace of the tune having been there, thus no concerns with warranty what-so-ever.

We also offer end user adjustable parameters, so if you choose to modify the tune further than what we provide, you have the ability to do so in the palm of your hand!

Let me (or Lew, 06MonteSS) know if you have any questions about any of our products!

Thanks
Mike
