Hmm with that turbo you should have plenty of low end... I still have a decent low end with a 6262 - and my motor setup is damn near identical.

my advice is go buy a 2.5 inch straight piece of aluminum about 4 or 5 inches long and buy a filter with 2.5 inch outlet and slap that on there then retune.

Using the stock air box will not allow you to be a "big dog" as you desire.

as i stated before you are starving your turbo it's the air box.

This is a thought, however I had a stock air box before my build with a bigger turbo than you have now. I had crazy low end.

Descendant Racing V2 turbo kit
.55 trim v-band Precsion Turbo
AEM FIC
38mm Tial wastegate
Forged diverter valve
3 inch Descendant Racing exhaust
RC750cc injectors
Descendant fuel rail
Walbro 255lph fuel pump
Dezod custom fuel return
NRG fuel pressure regulator
NRG oil catch can(not installed yet)
AEM Tru Boost controller
AEM wideband o2
Agengy Power crank pulley
Energy Suspension motor mount inserts

Engine Internals (thanks to Paul @ Dezod)

Wiseco 9.0:1 pistons
K1 Technology rods
Cometic head gasket
Arp head studs and rod bolts
ACL main and rod bearings
REV Dual Wound Valve Spring & Retainer
REV valves
Dezod vacuum block

Transmission

TRD LSD
ACT 6 puck sprung

Those injectors a little small for the build you dont think? Not sayin thats what is causing your problem; however for a built motor you can make big power. Those injectors will get maxed out fast.

The biggest power makers on these motors are:
1. Removing the Balance shafts
2. Headwork and Cams
3. Turbo (Bread and Butter) this is where most of your money should be spent. Never hold back on this one. Cut coners somewhere else. Like Valves.

looks like we found the phantom boost leak. switch it around and get retuned. it should be positioned with the unit running vertically, with the vacuum line running to the top, like this....
