So basically, the only "tuning" is the Vortech FMU, the Boost Timing Master, the accelerator nozzle assembly, and the high pressure pump to feed it all, right?
If so, that's not nearly as bad as the rest of the internet would make it out to be.
I like this. A lot. Too bad I'm on a stretched to the stars college student budget.

thanks to all for the positive support and kind words....
the current steps that I am taking to make more HP and torque and a faster truck are the following:
1. Smaller blower pulley to raise the boost- on the way!
2. Water injection to cool the boost- not yet purchased
3. Install a Higher stall torque converter to put the engine in the thick part of the power band quicker/ from a dead stop (flash stall of 1,800-2,400 rpm)- not yet purchased
4. tune the transmission governor for 5,000 rpm shift points
5. Tune the TPS sensor for quicker WOT mapping
6. Install good used 3.90 geared Dana 70 12 bolt with limited slip (trying to find one locally for a good price)

That is correct, aside from the 360 TBI throttle body and intake manifold...and it has to be the SUPER FMU to make it easier to tune with a regulator included.... probably easier than using a separate fuel pressure regulator, but I am not convinced yet.
I am not sure if we will even use the boost timing master in the end .... so far, at only 5psi of boost, it has hurt the power more than anything... if the boost goes way up to 9 or 10psi with the blower pulley change, I am going to see how it likes it to run at 1 or 2 degrees of timing retard per PSI of boost, but not allow it to start retarding timing until 4-5 psi of boost to keep it peppy and revving fast....
If/when we add the water injection setup, it will probably be much more effective at eliminating detonation than the boost timing retard setup....
we are still running stock plugs with stock gaps for now, but, I think we are about to move up to some NGk 7 series Heat range plugs... gapped a little tighter to hold the spark at higher boost/higher cylinder pressures
