2007 6.0L - CHECK ENGINE LIGHT KEEPS COMING ON

[bigredf250]

TRINITY PART#U7165 PCM_6_0
VERSION: V.1R07A
2007 FORD F250 6.0L

I HAVE THE TRINITY AND XTREME POWER PUCK STACK AND THE CHECK ENGINE LIGHT KEEPS COMING ON WHEN I HAVE THE TUNE SET ON PERFORMANCE AND EXTREME BUT DOESNT WHEN SET TO TOWING? TRY TO PULL UP TROUBLE CODES AND IT SHOWS NO FAULT CODES FOUND? CAN ANYONE HELP ME ON THIS ISSUE? IT IS VERY FRUSTRATING AND IT IS STARTING TO CONCERN ME.

You need to get the codes scanned with some tool that has full diagnostics. Programmers do not see all codes in PCM/ECM.
The code stored will have more info as to what the PCM/ECM is not happy with tune-wise.

Interesting, Id like to know what the code is, but my guess is low ICP, which tells me you need some fuel system upgrades to run all that power at once.

Yes,I get the same code,and I can't remember the number off the top of my head,when I have the extreme puck stacked with the preditor.The preditor code reader says no codes found but my modis reads it as low icp pressure.I believe that we are commanding more icp pressure than the system can deliver.Like the old 7.3L, they use 2 heui pumps when you need this kind of pressure and volume to fire the injectors.I may be wrong but I think the code is P2290,I will have to recheck myself to be sure.
