Hello all. I will start with my truck specs as that always helps. Despite my username my current cummins is a manual.
Rusty is a 1998 2500 215 pump with the NV4500. 360k miles. 53 block
So, ever since i got this truck i have felt that it was low in power. Found many boost leaks and had the turbo re-sealed. Now the truck pushes 28-30 lbs of boost. 4 inch exhaust with muffler. (pa law). BHAF air filter. EGT and boost gauge. New overflow,new afc line. Then i had new stock injectors put in. That made the truck worse. About the same power but now it will pop and blow blue smoke at 2200 rpm when cold in second gear. That increases to 2800-3k rpm when warm. Of course 3k rpm is all it has. Its a one owner truck before me. Pump has never been touched, Anti tamp screw still in place. Ive done an oil sample and the results were great.
Why i say low power. It has nothing under 1700 rpm. Put 3-4k pounds of trailer behind it and im pulling hills in 3rd. It has to be really wound up to feel the torque. Ive thrown thousands at this thing since i got it. Ive got thousands to go if i want it the way i do. But i have to make sure the engine is good. What i mean by the way i want it, is to have it nice yet in stock form . Maybe turn the pump up. 3k springs blah blah.
It is going to Cummins on the 26th.
Whats the point of the post. I have found lots of these low power posts. You read through them all. Get to the end and the OP has abandoned the chat with no resolution. Well, i fully intend on giving a full report. With a final result.
id like to see what anyone has to say. A place your bets if you will. If you need/want more info just ask.
