so I was doing some testing on my car tonight and my normal fuel pressure of 40 psi was way to lean on the wideband (first time I checked this car with it). Even when I turned it up to 46-47 psi, the car was still at 14.0afr at 5500 rpm in second gear.
my upgrades:
Stock block and heads (91 Fox)
GT40 Upper and Lower intake manifold
BBK 65mm Throttle body
BBK Throttle body/EGR spacer
C&L Cast aluminum intake
Pro-M 75mm MAF
E303 Cam
BBk Fuel pressure regulartor
M.A.C. Shorty Headers
Dynomax 2.5" H pipe and exhaust (dumps at angle just before rear axle)
*has resonators before H on each exhaust tube
MSD 6a and blaster Coil
*Timing is set at 12* on 93 octane
Could it be reading leaner than it actually is because I am getting my reading at the tail pipe?
The fuel pressure gauge use to read 2psi less when I had it on the fuel rail at the Schrader valve location. The gauge now sits on the BBK regulator.
