on stock

injector pressure 1800 by top end 2650.
pulse width 2.7 ended at 3
wastegate stayed at 98.8%
duty cycle 30-end at 38%
injector pressure spike for about 2 seconds a little less at 2694
no codes came up on stock run ran it 3 times it spiked all three times close to that pressure.
when just driving an hit it about 1/4 to 1/2 throttle it on either setting it stays around 2550-2800.

All of that sounds normal for stock vs. higher-HP tunes.

The wastegate code comes up because of the high boost (uncontrollable with the extra fuel).

Your injection pressure is low in the 100 horsepower tune, but it's due to the high pressure oil pump not being able to keep up with the demand of the injectors. Don't feel too bad though, my '00 F-250 won't even maintain 2000 PSI in a 50-60 HP tune.......

so everything is normal? just need to replace the hpop if i want all i can get out of the chip. do you all sell or recommend a hpop.

We don't sell or really recommend pumps (since we're not in that business), but we do work with Bob Riley at Dieselsite. He sells the Adrenaline pump which we've found to be a really decent pump at a good price. That should help with mid-high demand BUT.......

Your REAL issue (as well as everyone who owns a stock-ish 99-03 7.3L) is the injectors. The split shot design is good for idle noise and emissions....but HELL on high pressure oil. As the injectors start to wear, they "use" more oil. Mine are at 241K miles and as I have mentioned elsewhere....anything over 3.4 mS of pulsewidth and I am running 2000 PSI max. I never really NEED the power, so for now, the injectors work just fine (save for low-temperature starts) since I can't afford a good set of singles right now.

so im getting ready to put in new injectors and hpop. am i going to need to re-burn my chip or is it fine. and what do you charge?

I'd put the injectors in first & then go from there, your pump may be just fine for the single shot injectors. You will have to have the chip re-burned but I think PHP has a deal if you buy the injectors from them they re-burn the chip free, I THINK.

my truck is starting surge some in 100 horse setting at low rpm at steady throttle around town between 1200 to 1900. seams like its worse at lower rpm. the higher the rpm's are the better it gets and goes away. 01 ford 6sp 4x4
