Rollbacks
 

Bill, thanks for getting the two rollbacks done last week. Completely different truck. Throttle responce from down low is awesome, shifting is awesome, start up and idle is much smoother. Engine is quieter also. I can't wait till you get those custom tunes done. Just shoot me an email when there done. For anybody looking to get this done, it is well worth the money. Again thanks BILL!!!!!

Can you give some details about your truck?

Yes, please describe your truck.

PHP ROLLBACK BASE TUNE
PHP FICM FLASH
PHP CUSTOM TUNES TO COME HOPEFULLY SOON
Right now I have a Edge CTS on the 100 hp tune and my truck pulls as hard as it did with Bill's 140 Extreme tune. Except down low throttle response is much better . So when Bill gets my tunes done with this good base tune , my truck should pull even better. Before with old tune truck was at 453 hp on our Dyno.

Future Mods are a billet HPOP from Bob at Dieselsite,he is still in R&D just talk to him 2 weeks ago. PowerMax Turbo sitting on bench, Swain Coated Exhaust housing , manifolds, y-pipe, crossover pipe. With a few other mods as well. This is still with the OEM injectors in the truck. Knock on Wood.

Thanks FC for the description.


I just got my 58v php tuned FICM & rolled back ECM done and the only thing I noticed was my cold start issue went away.


Granted my truck is mainly stock but seems like after I got my FICM & rolled back ECM my throttle response was worse.:shrug:

Have you checked or cleaned your EBP sensor? When Bill rolled you back you most likely went to a strategy to uses the Exhaust Backpressure Sensor again. If you had a weak or plugged up sensor you'll notice a performance loss.

just a thought

I'll check that this weekend. Hopefully it is dirty & that's it. Found this link here to check it.
