Torque & acceleration after 2000 rpm

I've got one of those "reassure the first-time diesel owner" questions -- still trying to "feel" through the differences between the CTD and the gassers I've owned. I'm running the '02 ETH/6spd with 3.54 gears, an Edge Pulse, pump wire unpinned, RV275 injectors, BHAF, and 4 inch exhaust -- and gauges. I know that peak torque is reached around 1400 RPM and plateaus after that -- but my sense is that I've got more acceleration and torque from 1400-2000 RPM, and significantly less after that, in all gears. A diagnostic indicates that the Edge is working fine, my boost gauge shows no issues -- wastgate has been closed -- and the fuel pressure is 16 psi at idle and 11 at WOT. No codes. Do I need to find something better to worry about?

Thanks -- GP

The best torque curve is between what you are stating,after that it starts leveling off.

Horse power keeps rising with rpms...torque will rise level and begin to fall with rpms....the sweet spot is with hp and torque close together 17-2000 rpms

Re:Torque & acceleration after 2000 rpm

After taking noumours test rides, I think it's a lot easier to feel power mods on an auto because you don't have to let off the throttle when it shifts. Of course I HAVE ridden with people who DON'T let off when they shift, and it's just like trying to ride a bull i think.
