When you turn the dial to increase HP to 30%, does it affect the idle or engine running sound at idle?
Reason being I have another brand of tuner and when you turn past 15% the idle sounds like it’s on steroids.
I’m not comfortable with that. Sounds like the injector pump is making the engine almost knock more. ( Steve, 04/23/2023 )

We have never experienced this before with the AG Diesel module. It only is adding additional fuel pressure when under demand, so at idle there should be no changes taking place.

MD3060 6sp trans upgraded gears for durability. Have already: 103 springs, HD push rods, o-ring stud head, 120 injectors, fass lift pump, 178/208 cam, s355+s366 compound. Have reached a wall on how I can increase power for towing - currently at 360 hp and looking to get closer to 500 hp. Can your product improve on what i already have? ( William, 09/25/2021 )

The module that we have available for the 5.9L ISB engine in your Freightliner FL60 is the 20300: https://www.ultrarvproducts.com/20300-Area-Diesel-Power-Module-ISB-5.9L-(98.5-02)

This module will add up to 65 horsepower which is nowhere near the gains you are trying to achieve. The only ways I know of to get the kind of horsepower you are seeking from that engine would be to find a custom ECM tuner or convert the fuel system from electronic back to the earlier P7100 mechanical fuel control system.

Does your system allow for a bypass of the Deregulate of the Engine when the DEF sensor goes bad? ( MIke Oyer, 08/16/2021 )

No, it does not.

does it increase torque ? ( Jim, 03/25/2021 )

Yes it does! It increases torque in the same percentage as horsepower.

will the product 12000 give the better fuel and hp and is it easy to install Thank you ( Terry Tallerino, 03/18/2021 )

It will definitely give you more power. Fuel mileage results vary, some say they see an increase and others say it's negligible. It is a simple installation, the most time consuming part is usually just getting access to the engine.
