Im going to dyno my truck next month. Im gonna be running 4.2 beta on my smarty. Which setting should i use for the most power? 7 or 9? Also my friend is running the tnt on his 06, which settings should he use to make the most power? I was thinking tim 2, torque on 1 or 2, due to low end fueling, he has a stock cp3, catcher on 9 and rail on 2 or 3, he stacks it with a predator chip. What does everyone think? This will be my first time on a dyno.

So no suggestions from anyone?

I used beta 4.2 around two years ago, and netted the best power off of 7 coupled with 2/0 on the TST and 2 on the EZ on my truck - keeping in mind I had all kinds of supporting mods to hold it together, etc. Think most people just running SMARTY stick with 7 for the best power.

Good luck!

If you dont have the Cp3 to keep up with the high demand from Beta 4.2, there is no way it will keep up with a stack.
