Interesting, I figured there would have been a bigger difference jumping CPL's but I'm glad it is not causing any damage. Thank you!

For curiosity, would a someone manually adjusting numbers and parameters be able to safely squeeze some more torque and Hp out of the motor?
I have a base tune after a demandate through running rough and we're running it as is currently to get some feedback on how it drives and mph and let him know what I think. I'd love to get the torque up to somewhere in the 1750-1850 range as opposed to the 1650 I currently have. My motor is not smart torque enabled.
I just do not want to burn my motor up sooner than expected just to chase some power.
Any advice in this regard would be fantastic.

I purchased the truck in Sept. with 85K miles on the odometer and before I go it home it was in full derate from emissions codes.
Had it towed to the closest shop to help me get back online, the estimate was $2800.00 to get it running and no guarantee that more issues would crop up soon. The shop recommended DE-MANDATE. So I went that route. The truck has ran really inconsistent ever since. Sometimes low on power and really noisy and some times runs better but still not right.
CPL 4343- QUICKSERVE HAS NO INFORMATION ON ABOUT THIS CPL! Over the course of the last 80K miles running the truck under these conditions I decided to find a different shop to help fix the running poorly issue.
I am on the 5 version of this new shops programming. I am equipped with the needed technology to do programming remotely.
My main issues are now with the current file are the truck goes into a torque limiting mode at about 85% engine load and stops adding fuel. And does not have enough balls to hold 75 mph if any wind is blowing. Bottom end torque is good. Really poor MPG 3.4 under a load.
I am 90 % certain that the programming shop failed to do work order before first tune and therefore has no image of original program.
I need help!

The N11411 program = Advertised at 400HP/1650trq. Its actual is 435Hp/1654trq. Power peaks at 1400RPM (roughly the 1400-1700 rpm range).
The N11648 program = Advertised at 500HP/1650trq. its actual is 508HP/1674trq. Power peaks at 1600RPM (roughly the 1600-1900 rpm range)
The N11648 program also has an abrupt 1900 RPM cutoff in power/torque where the other N11411 program does not have this.
Otherwise, they are fully compatible.
