What We

Standard mail-in performance tunes are available for all Trailblazers, Colorados, Canyons, and virtually any other GM engine from Model Year 1996 and up.  You get increased driveability, better throttle response, and up to a 30 HP gain!   Trailblazers, Colorados, H3s, or any vehicle with an inline atlas engine are just $99.

Got new mods, since we saw you last?  All existing customers can update their tunes for only $49 shipped!

Remote tuning is recommended for customers who are building a turbocharged project or making major engine modifications such as new cam profiles, compression changes, or headwork.  Customers who can make it to the Savannah area are welcome to schedule an in-person road tuning session.  Others are will find the remote tuning option more convenient.  Note:  remote tuning requires the customer to purchase their own copy of HPTuners.
