I have a 2002 GMC Sierra, a Diablo 7198, hardware version 1.0, software version 1.03

I currently run a UPD intake with K&N, a Flowmaster exhaust system and 89 octane fuel. I have never installed the "tune" portion due to I was running Nitrous Oxide. I've removed the nitrous and will not be reinstalling it.

I'm wanting to know what updates are available and what those updates enable. I'm looking get a little better mileage and add electric fans in the near future.

Mmmm, hello? I bought the tuner in 2002 and I can not locate he receipt.

Please fill out the RMA request form under the downloads section of this web site to recieve an RMA#.
The new 2.13 revision includes updated tunes for better mileage and performance, as well as several new adjustable parameters.

Thanks
