lq4 turbo build will it hold up?

Hey guys i got an 05 6.0l from a van im running the truck intake, truck Tbody, siemens 60# injectors, Edelbrock Fuel rails, Aeromotive a1000, Aeromotive Regulator with 1-1 boost rise. i got arp head bolts, arp rod bolts and an mls head gasket set installed, with the f-body oil pan, borg warner s400 turbo 76mm extended tip, custom headers and exhaust 5in downpipe to dual 3in slp resonators, tial blow off valve and wastegate i have all the springs and blow off valve is adjustable. big front mount intercooler with all 3in cold tubing. i have the slp underdrive crank pulley, the now performance stage 1 Methanol injection good up to 15 psi, the Comp turbo cam Grind# 285LTB HR15, hardened pushrods, comp springs, and titantium retainers. The tranny is a built 4l65e with a 3800 stall convertor. ive been told itll be fine with proper tuning on 13-15 psi with 93 and meth injection just looking for more oppinions also my friend has an l92 top end that i can get cheap what kind of power will that add

6.0 is great for boost, pistons are the weak link IMO. sounds like you have a great combo going. I dont use the 1:1 rise on the reg, it just complicates tuning, better to have a solid stable pressure. 13-15 psi is too high for stock pistons to live long in my exp... The 317 heads are better for boost b/c they have a thicker deck, L92 heads have a thin deck that is said to not take as much boost and cause head gasket failure. Good luck with the build

I see this is an old thread, but I have a question. I thought the 1:1 ratio on the FPR was to maintain the pressure difference across the injectors. If the pressure in the intake manifold increases x PSI, shouldn't the pressure in the fuel rail have to increase x PSI to maintain the same flow through the injectors?
