I want to say you just need to adjust the fuel pump, but I would suggest a bigger exhuast and a air intake to help the engine breath better.

At moderate power levels,the factory exhaust is fine.Just lose the cat if equipped.

A BHAF is a cheap addition for good airflow.Sliding the plate forward is probably the easier\cheapest way to get power,or install an aftermarket plate.

Before you get into it,do some research.You will need to see just what your trans\clutch can handle,and get some gauges.Once you start,it can get expensive in a hurry.

Do some searching here,and some other Dodge diesel sites,there is a ton of info out there.

Ohhhh, I didn't see that you have that 5" exaust tip, that changes everything. Sorry, I couldn't resist.

Since you have the basics taken care of, just get a fuel plate & GSK kit, and that 12valve should run real nice. If you are real handy, you can grind your old plate & do the GSK without a kit, but it's not that much $$ and much easier to just buy this stuff. This is the beauty of the 12valve, no costly electronic gizmos needed.

Hey Weezl

Chris is right that it can get expensive in a hurry.

I am on Tranny #3 with a #4 plate and a 3000GSK. I had Dave Goerend build Tranny #2 and #3. I trashed 2 hard plowing, he has not yet torn it down to see where it failed, but he has stood behind his product 100%.

So, if you upgrade your motor be ready for the consequences.

that being said, my truck is a beast. My mechanic made fun of me for buying a dodge, then I built it up, now he just laughs at how fast it is. Very fun to drive.

While you are doing all this upgrading, make sure you take care of retaining your dowel pin.

Have fun, and feel free to pm with any questions.

If you have a reputable diesel shop around ,it is worth having them set your timing to 17 degrees as well.This will help slightly with fuel mileage and power.The timing works very well with the GSK also.

PC,im not sure why your trashing a built auto,but something isnt right.I push my Dodge hard plowing,I run heavy and work it hard,and ive yet to lose my built trans in 5 season of pushing snow.

I agree as does Dave Goerend. I stopped by my shop yesterday, and the tranny had been picked up to go back to Goerend. I am looking forward to hearing why it failed.

What tranny temp do you start to worry about your tranny?

If I hit 220 in the pan,I will take action,either get on the road in lockup At least 30 mph),and it should cool down to the tune of 5 degrees a minute down to about 170 or so,easily,as long as your engine temp is normal.I have hit 210 once in 5 yrs,and it was as i was finishing a job,so i finished and hit the road,in the 2 miles to my next stop it wa down to 170.If it starts getting hot at all,just drop to low range.
