OK so Im building a turbo LT1, im using a TC78mm on a forged 355. im looking for 700 hp. engine and fuel system will support 800+(dual intank pumps). ive been trying to find the best PCM system and after all the research Im still confused on what would be best for me.

my first choice was the FAST XFI, it can do everythign I want and still uses the opti. problem is its $2000+. Ive got the same problem with Big Stuff 3. they both can do everything I could ever dream of but both are stupid expensive....

my last option was a MS system that piggy backed my stock stuff but I havent been able to get a parts list or even a thread that goes through exactly what I would need to do for my turbo application. most of the info ive gotten so far has been piece mealed togther and leave me wondering if the MS can do everything that the $2k+ guys can....

heres what I want, I want to be able to switch from a 10psi, 14psi and 18psi tune on a momnets notice. I want to be able to control a boost controller. I would like the unit itself to be ready to go where all I would have to do is standard wiring,(no messing with cuircut boards) I would like something that i can easily tune, and the software is relitively easy to navigate.

what are you high hp guys running, what are the parts/pieces and how much did it cost?
