I'm looking to add a Nitrous Outlet plate setup to my LS1; Currently car made 420whp with: K&N Intake, PRC Stage 2.5 LS6 Heads, TSP TorquerV2 cam, Kooks 1 7/8 Headers and Off Road Pipes, SLP LM2 Exhaust.

Since then I've added:
FAST 102mm Intake Manifold
FAST 102mm Throttle Body
DW65c Fuel Pump
(Have not gotten larger injectors yet....looking at something around 40 lb/hr.)

I'd like to hit it with a 150 wet plate from Nitrous Outlet; Car is tuned with HPTuners currently.

Looking for suggestions and/or experiences with local tuners on nitrous....I'm trying to keep this stock cube/stock internal motor from blowing up.
