I want to start doing the mods and need to know where to start first I tow a 13000 lbs fifth wheel and have an early 99 w/373 gears I want to get the DP tuner chip I will ask Jody what to get for settings Should I get gauges first? or can I get the chip without the gauges I will be getting a new exhast system in the next few months I think it will be the 4" I just need to know where to start Thanks
Ihave the same truck, start with boost, pyro and trans temp gauges. get intake and valvebody for trans. Tell jody when you get your dp tuner about the valve bosy and get a v-10 trans cooler or the 6.0 trans cooler. that would be a great start up and you can work from there. Also from what i've heard you can have Jody retune the chip for additional mads as you go so the is a great choice.
I routinely recommend gauges, air intake, exhaust and chip, in that order. Clearly, this is totally up to the customer.
Your gauges will let you know what is going on under the hood and out the back. When your towing, this info is helpful.
The air intake and exhaust allow your truck to inhale/exhale, and just like us, it performs much better when it can breathe. Performance and fuel economy are usually improved with these additions.
Lastly, the chip can provide some additional "oomph" and changes to shift points to help get up some of those hills. A few customers with '99s opt for new turbos instead of chips...to each his own.
Thanks for all the advise I bought the 6637 filter and now I am tring to get a piece of pipe the local muffler wants 40.00 for 1 foot piece I am sure I can find it cheaper
Ask the local exhaust shops to give you a piece off their floor, if your going to be putting exhaust on soon, go to the shop when you get it done and get one of the scrap pieces. The piece of pipe only needs to be about 3 1/3-4 inches. Otherwise some people have used PVC with and outside diameter of 4 inches as well. You may want to get two pieces 4 inches long incase you want to do the CCV mod later. Most exhaust shops have all kinds of 4" exhaust pieces laying on the floor. Otherwise go dig in their dumpster out back.

When you do the 6637, do you have to it any, or you just stick it right in?
And the pipe your talking about, is that for the intake? Anyone got pics of this?
