I've got a Diablosport Predator(let the flaming begin). I'm happy with it, since the 7193 can record data-logs. I am also going to be changing tire size in the near future, and maybe gears, so being able to make some adjustments on my own is nice. I'm happy with what I've got, and I can tell a big difference in the way my truck performs.

The only "Tuning" part of that are the last 4. For tuning your changing your engines VE table so it properly adjusts fuel input for air intake.


Everything in that list are mods

 

ah, well i know those are my mods but i wasnt sure if a list of mods would help with tuning or not. are there any other things i could change other than the rev limiter ,speed limiter, shift points, and torque management??? and does the shift points seem too high or too low??

 

Tuning will improve almost any mod you do. If you get headers you'll feel an increase, Tune for those headers and you'll feel another increase.
Get a bigger cam and you feel the increase. Tune for it and you **** your pants

 

With a stock cam I shifted at 6000 1-2 and 5900 2-3. Edit. You also want to "zero out" your shift times, so it shifts faster.
