We do GM performance programming and can help you get the most out of your vehicle, including engine mods trouble codes, speed limit removal, Rev limiter, transmission shift firmness, cooling fan temp and much more.  We have no limitations when it comes to the vehicles we program.  If you are interested Send us a message or contact us by phone. 

-Please Note:

The 30 minute security relearn procedure will need to be done before the car will start with the replacement computer.   This requires no tools except that a battery charger or jumper cables from another vehicle should be on the car because the key will be on for 30+ minutes.  It can also be done with a scan tool if you have one. 

A crankshaft variation relearn may need to be performed once the vehicle is
running. This will be evident if the check engine or service engine soon light comes on once the vehicle is running. You will need access to a scan tool to do this and clear any related trouble codes (Code P0315). If this is not available to you a repair shop will have to perform this and clear the related trouble code. The vehicle will run normal but the ”service engine soon”light will come on and a trouble code will be stored until this is resolved.

We can disable both of these for a small programming fee but it is not recommended unless all other options are unavailable.
