I am not too impressed with the power (lack of power) of the Cummins in my 590. This thing just seems so sluggish! I've found many power upgrades for the 4bt, such as injectors and fuel pin. Is there a good reason not to do this? Is it just about fuel economy? Would the rest of the drivetrain hold up to an extra 20hp? :beatsme I just don't think I should have to shift down to first to go up a slight incline. Thanks!
