So I recently added a custom tuned pcm from pcmforless. I have to say I love this addition, overall driveability is greatly improved, acceleration in all RPM ranges is much better than before. If you have a colorado/canyon, I highly recommend this mod.

This is my 2005 GMC Canyon, Options included on this truck are the 3.5l 5cyl engine, auto trans, 4.10 gears, G80, power everything, and tow package.




Aftermarketwise,
A 4in Skyjacker lift has been added, with bilstien shocks up front and skyjacer shocks in the back. The truck was two toned silver and grey and the door handles were painted to match the truck, also a sung top tonneau was added. The bed was coated with a TUFF SKIN spray in bed liner.
For help on those late night trails the highs, lows and fogs have all been swapped to silverstars, in addition to that a MR Taillight kit was added giving the option of running the highs. lows and fogs all at one time.
For the performance portion a Ravin exhaust system was added along with an AIRAID throttle body spacer, AEM DRY FORCE intake, and a custom made ram air setup.
