I HAVE A 98 CUMMINS 12V. AUTOMATIC THAT I BOUGHT RECENTLY TO TOW MY WHEELIN RIG... I WAS WONDERING WHAT I COULD DO TO HELP IT OUT AND TO BLOW A LILL BLACK SMOKE!!!! THANKS!!!!!

 

you already have good injectors i would just grind the plate and tune the afc.

 

read the stickies, but the stock tranny wont take too much over stock

 

x2 on stock tranny but you can mess around with your afc, starwheel and slfuel plate. Just dont get crazy with it. Smoke is nice at times but its wasted fuel.

 

x3 on the tranny.....there's a bunch of links on tuning the AFC....here's a pretty good write-up with a bunch of pics
afc mods (lots of pics) - DieselRam.com

You can also get a BHAF which will help bring in some airflow....plus it makes the turbo sound BEAUTIFUL!!

 

Add air first, then add fuel. Like everyone above said, also transmission and if you don't have them, gauges.

I'm towing an off-road rig with mine and it does a really good job with the mods in my sig. New mods will be to add airflow, which (I know, I know) I should have done first. I have power all over the place, but I have to backpeddle to not burn up stuff with EGT.

Ebay them i know people dont like glowshift but i havent had any problems with mine

 

Best place to find a BHAF is the local Cummins store. You can get a good fleet filter there for less than you can at NAPA, etc. There are a lot of threads talking about the big filters, do a search and do some reading. Cost shoud be in the $55 range, and that is a bolt on deal, no mods required except to pull your air box.

Gauges, best idea is to post a thread so that one of the vendors can quote you. Some really good people support this site, they have the good stuff and the prices are great also.
