12-13PSI based off the math of the pulley size- I'll know when it's being tuned

12-13 you sure thats a lot for whipple stock pulley. Without headers too your egts gotta be through the roof.

on the front coil can you route the resovoir line through the perch, looks like it might get chaffed or pinched by suspension movement.

on the rear plan on keeping the akward stock location, seems like for a $2500-3k setup you would want to mount those on same side and with much beefer mount points, i know if i was wheeling that would be first thing to snap off,

got the trick bumpstops also? Diy beadlocks too?

Also gonna need some serious cooling mods all that heat.

With long tubes, no cats and modified whipple intake truck made about 515WHP on meth. Headers helped bring the boost down a little also

Icon 2.5 coilovers and UCA's, rear 2.5" shocks
Method beadlock wheels
35" General grabbers

Then added 2.9L whipple, and now starting on the fuel side to help with any other future upgrades.
4" pulley
high/low side fuel system LT4 Pump
new tune

Is this a 4x4 or 2wd
What's the preference for a performance truck?
