i just bought a bone stock 1997 one ton cummins with 150,000 miles. im going to pull a 21 ft capri boat. need some help and advice on what i should do to it perfrmance wise. want more power and for it to smoke more. thanks!!

 

More smoke will = more boat washing.

Is it a 5 speed or an auto? This equates to new South Bend clutch or DTT tranny work

What I have done: Start with a set of gauges, air box of your choice, 4" pacbrake, 4" exhaust, Phat Shaft turbo with 4" outlet. Custom ground cam plate (free power), gov. spring kit and timing advanced.
This has put me close to 400 usable towing horsepower. I still have egt problems on the big hills at high elevation, but even having to watch my pyrometer, I'm still passing everything on the road.

 

Need to see if the kdp(killer dowel pin) issue has been dealt with.

 

whats the KDP issue?

Get gauges first!!! EGT and trans temp, boost is also good.

The auto will only hold 50 or so more hp than stock, so plan on a new TC and VB, and as long as it's out you might as well rebuild it.
Also consider a 4" exhaust system.
