    When it comes to handheld programmers, by themselves they offer better improvement than nothing at all. However, a custom tune is where you get the most bang for your buck, as every truck is a little different and a canned tune on a handheld programmer is so generic that it can't possibly maximize improvement for any one vehicle -- but a custom tune is specific to YOUR vehicle.

    You might consider getting a DiabloSport InTune and a custom tune from @06MonteSS (aka Diablew), who is a custom tuner and patron of this site, as well. I'm quite happy with his work on my truck and I believe he sells both the handheld device and a custom tune as a bundle that's cheaper than if you bought them separately. You work with him for the tune by doing data logs and then sending him the logs ... and he sends back the tune. You don't need to be a computer expert to do it ... he can walk you through it if you're not sure of the what/how.

    correct ^ ^ ^....

    With the custom tune done for the intune/trinity and your truck, you'll gain even better/quicker throttle response & acceleration, stronger/harder pull, smoother & quicker power delivery throughout the rpms, etc... and sometimes, maybe even a little better gas mileage - if you can keep your foot out of it! hahaha...

    as far as gains go... absolute hp/tq gains are hard to predict... every vehicle is different... even if they're the same and have similar mods... location/weather, fuel used, elevation/altitude, etc etc all play a role... the same holds true for mileage gains - those variables, plus driving habits/style, how much highway vs city driving, etc all make a difference.... you could gain no mpg increase, or you could gain up to about 3 mpg increase... tough to say due to the variables in play...

    I CAN tell you that you will definitely have a very noticable performance difference/gain over and above the canned preset diablo tunes...

    I have gained people anywhere from 15-39hp, and 12-23lb. ft. torque...and 0 to 3.5 mpg... again, obviously mods, fuel used, etc all played a role in who gained what...
