Your biggest issue with the 89 having the injector pump turned up is your Exhaust Gas Temp climbing.
The main issue I've heard about with your truck in particular is that it can get high EGT's(hot) quickly. Thats why they came out with the intercooled models and have stuck with that ever since. The best mod you can start off with is an intercooler. BEFORE you do any mods, get gages. EGT, boost at the least.

IF you dont do that, you'll likely fry some pistons with the pump turned up, and your stock clutch won't hold up.

You want the boost gage because with more added fuel you NEED more boost pressure to help keep those EGT's in check. But, your stock turbo is limited. I dont know about your turbo for sure, but on my 97 the stock turbo is not designed to go over 35psi. I will never replace it with anything but stock because I wont be pushing over 350 horsepower(800 something ft-lbs torque).

Lastly, and I hate to sound like a pessimist here, is the older 3/4 ton trucks were equipped with an inadequete rear end. If your rig is a 1 ton dually, you may not fall into that catagory but I'm not sure. They used to put Dana spicer 60's in the gen 1 ram's with the cummins and they learned quickly that it wouldnt hold up.

My rig : 97 Ram 2500, 12v Cummins, P7100 injector pump with #10 plate full forward. Boost elbow cranked up to 35psi. Big air filter, 4" exhaust. Beefed up 47re auto. Boost, EGT and tranny pressure gages.

Approx. 250hp 525ftlbs

Thanks for the info. I believe my rear end is a Dana 80. No worries there. It's looking like I can coax a nice 50-75 horses out of what it is now, but gauges are a must and an intercooler is a good possibility.
