1: 30 HP Eco Tune
This tune has a slight power increase but focuses on fuel economy with enhanced transmission tuning.
2: 60 HP Tow Tune
Focuses on a moderate power increase that is safe for your stock 48RE transmission and a completely altered shift schedule that gets your transmission into lockup in 3rd gear that holds while coasting, unlocks for a split second to smooth out the 3-4 upshift and doesn’t shift into 4th until an optimum speed has been reached. Also adjusts the manual second gear lockup point lower… Lockup sooner equals much lower transmission temperatures and more power to the ground.
An additional benefit of this tune is a completely reprogrammed cooling fan to protect your transmission. We all know that HEAT KILLS. On this tune, the cooling fan will begin ramp up when the Transmission Temperature or Engine Coolant Temperature start to rise. Stock programming waits until you are very close to the trans and engine overheating before fan ramp up even begins….
You can watch these fan settings in action here:
3: 90 HP Street Tune
This tune focuses on daily driving performance. It has approximately 90hp increase for a very noticeable, fun driving experience. This is the upper limit of what is safe for your unloaded truck. This tune includes the enhanced 48RE transmission tuning.
4: 160 HP Sport Tune
This tune Shifts its focus from daily driving to those looking for a “hotter” tune than just a daily driver. If you want to see other cars get smaller in your rearview mirror, this is your tune. Recommended for use on a built transmission.
5: 210 HP Race Tune
Like the 160HP Tune, but it goes faster… Recommended for use on a built transmission.
12-Valve Tunes: (Yes they are for a 3rd Gen 5.9👍)
6: 12-Valve Tune Stock HP
This tune gives you a traditional diesel sound and has a small power increase over stock and also has enhanced 48RE shifting patterns.
7: 12-Valve High Performance Tune 120 HP (One of the most popular tunes)
Identical to the 12 valve tune above, however it has increased fueling and limiter values. You get a traditional Diesel sound and the fun of a performance tune in one. This is my personal daily driver tune.
*Trans Tuning not available for 2003 trucks.
** Cruise Fueling applies to 04-07 trucks.
