Need Help Diagnosing Your Vehicle?

In all honesty, 95% of the work performed by a tuner is related to diagnosing and troubleshooting. We realize that sometimes a tune can't fix all of your issues. Luckily for you we offer our expertise to locate these problems for you.

 

Before you go ahead and throw your money at us, please read the following article and learn what simple steps you could take to save yourself some cash! Some of these issue can arise after a mechanic visit, an LS Swap, after installing mods, after getting tuned, or even throughout a stock vehicles life. Please note that this can apply to any makes but we are specifically referring to GM here.

Some common issues include:

  • No Start after a Cam Swap
  • No Start after a LS Swap
  • No Start after a Tune from a local tuner
  • No Start after adding some modifications (Full Bolt-Ons)
  • Difficulty Starting Up during Cold Weather
  • Difficulty Starting Up after turning on the AC
  • Irregular Vibrations and Noises
  • Lack of Power
  • Issues Idling properly
  • Shuts off after  AC is turned on
  • Shuts off after reversing
  • Vehicle keeps accelerating during a stop
  • RPMs Do not Drop
  • Irregular shifting

 

These are just a handful of issues we have seen over the past 10 years tuning. Issues could be fixed by sometimes fixing a sensor, replacing the computer, fixing wiring, or getting a proper tune. However, sometimes you may need to fix a couple of issues that may seem like its one but it actually two or three.
