Does anyone know or have lower compression pistons on their SC lude? A lude with 9:1 C/R and one with stock C/R, both are Supercharged with identical mods and both are at 6-7 psi....which one makes more power. If it is the same then what would be the use of lower C/R pistons, would it be better to get forged pistons retaining the stock C/R? Thanks for your help....and could some one differentiate between the Cartech FMU and the JR unit? What are the differences? Thanks

The higher compression engine SC'd will make more power than the lower compression one. You lower your compression to run more boost safer.

At 6-7psi their is no need to lower your compression. Start talking about 10+ and then maybe.
