This is the response I sent from your PM to me earlier:
I haven't gotten one single email from you. If you're sending them to Bill or Corey, I can understand that they may not have been answered yet, but I haven't gotten even ONE. Corey doesn't answer many emails because of health issues (heck, she hasn't been in the office for 2 months and works from her laptop in bed when she feels physically able to work), and Bill gets nearly 100 legitimate emails a day so some of those go unanswered sometimes.
How did the shop measure fuel pressure? There isn't a sensor for that so scanning it won't tell them anything there. Oil pressure "on the high side" means little. Do they know what they're looking for? 3000 PSI is normal under heavy loads for aftermarket tuning and if they're getting that, then that's good. It's very unlikely that your stock high pressure oil pump is able to keep up with the injector demand in high-HP programs though, so 2400-2500 PSI would be more like it (if not a little lower)....which is NOT high. If the truck is only able to muster low ICP under load with a high IPR duty cycle, then that issue needs to be addressed. Keep in mind that the 99.5-01 Powerstrokes are only capable of a realistic 100 RWHP gain anyway and the higher-hp tunes are only designed to fuel more off of the bottom end.
Conversely, if they were to test the system in a stock tune, 2600-2800 PSI would be normal (and good) under heavy load.

We wouldn't have had that problem had we known what the injectors actually were when the tunes were initially built......Bill called Brian last night to let him know the new calibrations were on the FU2 server for him.
