"Two year unlimited mileage warranty and the Suncoast name/reputation behind it! I believe that the full transmission is the way to go. Everything is buttoned up nice and fresh, just add your choice of Torque Converter and Accessories and you are ready to install! I recommend the Pro-Loc Velocity (upgraded) Converter, PML Deep Cast Pan and Transfer Case Support Brace whenever budget allows."- JK

Adjustable boost capabilities for electronic 6.5 engines! Allows the user to increase boost levels for increased performance. Works on all electronic 6.5 models 94 up except those equipped with MAF (mass air flow) sensor. Click on heading for more details.

"While this unit works on all model years, it is particularly effective on 1996 up trucks with HD "F" engine programming. It is my suggestion that 94-5 trucks take advantage of the TD-Max Performance Chip Prior to installing this unit as it will likely be unnecessary to ad the boost control with the proper chip calibration. Use on the 94-5 trucks and 96+ LD "S" engines may require a second controller on the firewall mounted MAP sensor to avoid an aggravated DTC 78 (wastegate solenoid) fault code." - JK
