HPOP Health Check... Thoughts?

Finally ran AE and did a "HPOP Health Test" on it...

https://docs.google.com/viewer?a=v&p...NTA0NmMxZjRjYg

Here are the results, based off the test parameters from the above link:

At Idle:

a. Engine RPM: 680
b. Injector Control Pressure: 480 PSI
c. Injector CRTL Pres DC: 10.55%
d. Accelerator Pedal Position: 9.81%
e. Exhaust Back Pressure 14.86 PSI
f. ICP Volts: 0.81 Volts
g. Engine Oil Temp: 195*F
h. Volume Fuel Desired: 11.1 mm3
i. Fuel Injector Pulse Width: 2.82 ms

Ok, so did it again at load, this is in 4x4 in 2nd gear, WOT, I picked the run with the highest ICP at WOT.

At WOT:

a. Engine RPM: 3440
b. Injector Control Pressure: 2056 PSI
c. Injector CRTL Pres DC: 30.47%
d. Accelerator Pedal Position:74.91%
e. Exhaust Back Pressure: 40.78 PSI
f. ICP Volts: 2.74 Volts
g. Engine Oil Temp: 191*F
h. Volume Fuel Desired: 48.1 mm3
i. Fuel Injector Pulse Width: 2.25 ms


*Note: Chip was OFF for these tests.

Attached is the full readout, feel free to take a look and tell me what you think:

40 psi of exhaust psi? Time for a stack out of the hood. Get that baby down around 5.

On a serious not though.... and I really have no clue just asking. Shouldn't the ICP be around 3000 WOT under load? And it show's your throttle position around 75%, should it read 100%

Again i don't have AE so I don't really know what to look for.

Pretty sure a hood-stack isn't legal, lol!

I would thing that even stock, it should be breaking 3000psi...I just wish I understood how to read the data better. As far as throttle position... I wonder if maybe need a new TPS? I haven't seen it go above 75% yet.

On a side note, with my chip on I can see in excess of 3,300 psi.
