Please specify the tune(s) you are looking for; most common tunes are:

• 0hp Stock Power
• 25hp Tow (With brake if LLY+)
• 45hp Economy
• 75hp Street (transmission tune suggested)
• 90hp performance
• 120hp Race

**Transmissiong tuning for line pressure changes strongly suggested for 75hp+ tunes**
*Transmission tuning available for LWN and LML Duramax's*
*2001-2010 Dmax's we do not build transmission tunes unless the transmission is a upgraded build*

Trans tuning has the following features:

• Modified Shift speeds (RPM/speed at which the shift is commanded)
• Modified Shift timing (time it takes to complete a shift)
• Improved TCC lockup strategy
• Increased line pressure at all times (Similar to what the EPC fooler does)
• Improved torque management, both during shifts and in gear, as well as the ability to tweak the trans tuning to individual customers request. We would require the stock reads to be sent in with the order.
