Need some AE analysis, finally did some data logging

So finally hooked up the AE. Truck was completely warmed up. Did one normal acceleration from stop, one WOT to ~70mph... then continued capturing until my SES went out. What is the consensus?

everything looks normal to me except exhaust back pressure. Seems high at idle. Usually reads atmospheric pressure.

Agreed. Something is up with your EBPS. Have you cleaned/inspected it lately?

You need to do an acceleration run from 45ish to say, 90 (safely) without it dropping out of OD. ICP is low unless you weren't really hammering it...

I did not notice you had multiple pages logged until now. On your WOT run, your ICP barely made it to 2000. Should be near 3000.
What size injectors do you have?

I agree,Jody just lived tuned me yesterday and i held 3200 psi in my 140 tune.2000psi would be almost a worn out pump.

Well there's no good news. I have swamps AD stock rebuilds, about 3 yrs old, and an Adrenaline pump that's not 2 yrs old! Well would the EGP cause me problems? It's been disconnected for years, and just this winter I fabbed up a new tube from the manifold to the sensor. (my old one looked like swiss cheeze) I cleaned everything well, so looks like the sensor is fubar.

I have a question fyrehose, looks like you have a 38R too, when your cruising at 65mph, how much boost and EGT's are you showing? I'm at less then 2psi boost, and 650-700 degrees.

I'll redo the run with 45 to 90. And on my WOT run, it was on the floor. But I was running Cale's tunes from YEARS ago

. I just received the most current tunes from Jody for my F6, and I'll plug it up for the next run and put it in the 140 tune. Am I capturing the correct information in my data logs, or do I need to change some stuff?

NO, it has no effect on the performance of your HPOP. It's been disconnected for years, and just this winter I fabbed up a new tube from the manifold to the sensor. (my old one looked like swiss cheeze) I cleaned everything well, so looks like the sensor is fubar.

I have a question fyrehose, looks like you have a 38R too, when your cruising at 65mph, how much boost and EGT's are you showing? I'm at less then 2psi boost, and 650-700 degrees. That sounds about right.

I can't see any tuner only calling for 2000 icp max. But you can try Jody's chip. It may just be that your pump is weak. Yesterday I pulled out an adrenaline pump for my friend that had less than 10,000 miles on it. It died while driving.
