Yes it is producing 7psi of boost at idle, not sure if it's old autometer gauge reading wrong. will buy a new vacuum/boost gauge soon
Cleaned up, thanks late night plus tired.
So I got this 77 280z it's got a 83 swap bought it few months ago here in San Diego. When I got it had head gasket blow would turn on but never drove it. I put a new gasket on and had the head checked and surfaced with the intake and exhaust manifold p&p 3angle here are the Mod or thing it has
List
Original ecu 83 turbo and AFM with a intake filter
Nissan t3/t4 turbo fat front monnt intercooler
Greddy blow off
Tial wategate 38 10psi Spring
Fuel rail 440 supra injectors
Fuel lab FPR at 36 psi at idle around 700 rpm
3in down pipe all the way back with hks hi power muffler
Aem Wideband
No power steering
No ac
No cold start injector
Plus all the vacuum line were disconnected just have autometer boost line from intake and brake booster vacuum the rest are blocked off

Can drive it fine around the block. will turn on rev well in neutral sound good and healthy. once I go over 4K stalls it fall in its face. I have an old autometer gauge it reads 7 psi at idle and will go up to 20 pounds when under load around 4K before it stalls. Will install a boost gauge with vacuum/boost maybe the old one is broke
Any suggestion thanks
