Gone & Done it ;) I jumped in!
I have an 04 GTO M6 that is all stock except for stg2 clutch, lightweight flywheel, k&n cai, & msd wires. Car has 94k miles and still runs like a top. 
Hopefully weather permitting I'll get my baseline dyno run tomorrow. I went with the torquer v.2 112LSA w/PAC .650 single springs for peace of mind. I was actually really dissapointed because going by their website
it says you can use the springs with the MS3 which is like .603/.6xx lift but when I called they said that they def would not recommend that. Also slapping on a set of stock 2003 Z06 243's w/8k miles to refresh the top end and help me with my numbers a little.
Any of you guys have to say about the torquer v.2? seems pretty popular but will I be disappointed? Any idea what the tuner should/can tune that cam to rpm wise?
As for your RPM question, the tuner will program for what the car wants/makes. Essentially you set your peaks by your head and cam choices, more than tuning.
