Texas Speed & Performance is one of the leading LS-based computer tuners in the country!  We can custom-tune your PCM based on your modifications and performance goals.  We have years of tuning experience on our chassis dyno for proven performance and maximum driveability!  Some of the most popular tuning changes include but are not limited to the following:

• Desired Idle Speed
• Desired Shift Points
• Rev Limiter
• Speedometer Recalibration for Gear Swaps
• Speed Limiter Removal
• Change Fan Activation Temps
• Change/Delete Torque Management
• Remove Skip Shift
• Remove SES Lights (off-road use)

For any custom tuning, you will need to send your PCM to us.  In many instances, we will be able to tune and ship your PCM the same day that it arrives!  If you have a 2005+ vehicle with an automatic transmission you will also need to send the transmission computer module (TCM) to us so we can make any necessary transmission changes.  When you send your PCM to us, please include a complete modifications list as well as a daytime phone number that you can be reached at should our tuner have any questions or concerns regarding your custom tune.  With any of our mail-order tunes, you will also receive ONE YEAR OF FREE UPDATES!  Within one calendar year of your original tuning purchase, we will perform any tuning changes for free of charge!  All you will have to pay for are the applicable shipping fees!  Feel free to give us a call at 806-698-0365 with any questions or concerns.

TUNING AVAILABLE FOR BOTH V6 & V8 MODELS!
