Here is what I started with:
87 GN, 57K miles all stock even filter.
New upgrades include:
new vacuum hoses
Duttweiler neck
K&N cold air
ported throttle body
50 lb. injectors with chip (93 octane/17 psi/for 50 lb. injectors) unk brand
Billet adjustable regulator
new pcv and Fram fuel filter
Walboro 340
hot wire kit
TE-44 turbo
ATR dual 2.5" S.S. exhaust-no converter
160 degree t-stat
ATR 3" mandrel bent down pipe with new wastegate control (garret type)
New plugs and wires
Screens pulled from MAS
The car starts right up and idles well with 17" of vacuum overall runs well. From a start and to W.O.T. the car is a bit flat with not much torque/power. When the turbo spools up, it starts to go well as the boost increases (set at 17-18 psi). When it shifts into 2nd and 3rd gear, it goes pretty well but it just doesn't hit hard like I thought it would. The 275/40R17 Nittos don't break loose at all. After all this work, I am disappointed in the car's performance. Is there something I am missing?
I installed an autometer fuel gauge onto the fuel rail using the autometer 4' braided and I do not get a fuel pressure reading. I have tried (2) different gauges and still no fuel PSI reading.
Also, should I adjust the boost with a needle and seat or should I only use the adjustable rod, having the computer to control the boost rates?
Any help would be greatly appreciated.
