im getting a diablo sport tuner for my car and want to no if there is anything i can do to the car myself and see improvemment in performance in tuning wise?
When you get the Diablosport it should allready have a performance tune in it. You can modify it from there.
You can adjust for gear ratio changes, spark advance/retard, richen or lean out your fuel curves, raise/lower rev/speed limiters... and some other stuff.
DO NOT JUST MAX OUT YOUR SPARK ADVANCE OR LEAN YOUR FUEL OUT!!!
Adjust it in SMALL increments and I still reccomend getting the car put on a dyno and checking the air/fuel ratio because I actually richened my tune up and it was still lean...
If you add too much timing, you can run into detonation. Also, dont just add a bunch of timing and no fuel... alot of stuff to consider before you start tuning.
I gained 6rwhp and 15rwtq by adjusting my fuel and timing.
