I would like to purchase a PPE tuner for my 08 LMM and want to get some feed back first. How does it work so far? What are your likes and dislikes? Has the check engine light ever came on?

My dad just bought a 08 dually, we put the ppe on it and just on setting 2 i think it will stay with mine we think it might've helped the fuel mileage a lil bit but its hard to say cause he stays on the road so much but there no codes and deffnately big power gains, and no smoke!

Its night and day with just the tuner (even the Economy)... depending on how you drive you will definitely see mileage gains and no SES light or anything of that sort. Our tuners all work within OEM standards as to not set any codes. What tuner have you been looking at?... and what exactly are you trying to get out of the tuner?

Will you still have the added power while the truck is in regen or does it go back to stock like the banks six gun?

No... you will not have the added power through regeneration because the intake has a butterfly that restricts the air flow when the truck goes into regeneration. when that flap closes, and no air is going in, it allows the filter to get hot enough to burn off the matter in the filter... the truck is greatly restricted during the regeneration process.

Thanks for the info, I didn't know about the restriction in the intake. This is my first diesel and this regen stuff I think needs to go.
