By the way, the Genisys happens to be my favorite scanner....well, short of what I know about the Snap-On Verus.

i only got it tested on 100hrs

injector pressure all the way though 45-80 stay between 2000-2300
fuel pulse width started at 3.6 and stopped about halfway and stayed steady on 4.7
manifold pressure started at 20 and at end was 31.23

injector pressure regulator started at 38% and finished at 58%
the injector control pressure stayed within .5% the hole time.

i will test on stock tomorrow.

it was hard testing almost everytime it would through a code and stop recording.
now all these codes in all the testing wouldnt make the engine light come. they were just stored codes.

The 2000-2300 PSI is your problem.
The programming is calling for 2900-3000 PSI in the 80+ HP tunes.....

You're losing a lot of volume and atomization.

i am heading out now to retest just to make sure. its had watching for cops and the road and the computer at the same time.

if this is the problem what is the fix for it. u have obviously done more over the computer than any shop i have taken it to. thanks for getting on this.

the results on the 100 horse were the same. i forgot to let you know the wastegate code and the 1211 come up on every test i floor it. the wastegate percentage stays up till about halfway then drops rapidly to 84.3 and stays there thats about when the code comes. normal?

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.
