I have a dyno event coming up the end of Feb and want to make the best of it to learn which tune i will run this pullin season. I have two tunes one of them has alot of fuel and timin while the other seems to have more rpm and seems a little more powerful.

How can you find out how many rpm the tune is able to turn up to i have search and can not find rpms limits or anything like it. Also i would like to add some fuel to the tune that runs more rpm to see if it would dyno more power. They say to much fuel will hurt the hp. The reason i think this tune could use more power is at WOT it will not get any hotter than about 1400d. I dont know if i should go threw the timing or a different chart. Help me please. And also is the Torque Limiting 4wd low mode be able or disable for sled pullin. Thanks everyone.
