I have a 99 with the 24v Cummins that is pure stock I would like to know what would be the best route to take as far as performance torque and horsepower without rebuilding the tranny right now. any suggestions would be appreciated

Midnite

Well, most everyone here will highly suggest gauges for a start. Fuel Pressure, Boost and EGT are good to get for a 98.5 - 2002 truck.

For performance, easy and cheap would be to pick up a used Edge EZ box. That advances injection timing a bit as well as increasing fueling a small amount. Also ditch the stock muffler--it's a restrictive design, and replacing it with almost any straight through type muffler will be a noticeable improvement.

That combination should get you maybe 30 HP and some mileage gains. You can't really bump up the power too much with the stock transmission (I'm assuming you've got an automatic) unfortunately. That said, don't underestimate the benefits of a good tranny rebuild. A good torque converter and valve body will make it drive like a whole new truck.

thanks man can you tell me why everybody is recommending the smarty tuner for this truck

Midnite

The Smarty is a great little programmer--it'll give you the same benefits of the older Edge EZ, but without the extra hardware. However, it also gives you a lot of other things as well such as pulling codes and speedometer correction when using non-stock tire sizes.

It's just a very cool, very high quality piece of gear.

Cjenkins

okay so what you recommended the first time would probably be the best route where would be the best possible place to find the older Edge EZ

Build the trans before adding power. EGT gauge as well. That way you can use the extra power without babying it and worrying or calling AAA for a tow to the trans shop while on vacation.

What do I say I want the tranny rebuilt at what standards

My signature is up to date w/mods. I did a ton of reading on here and added mods mostly to get me better fuel mpg. At the same time Hp increased. Overall I'm pretty happy w/the truck.

Can anybody tell me what they think about superchip programmers

Cjenkins

Should I also run trans temp gauge with boost EGT, and fuel pressure

Dane

Sell yours while it still works good and install one of these -

Dane how much do one of these run

The same way I feel about skyjunker, at most "so-so" product. Find an Edge Juice or Quadzilla Adrenaline, these will have gauges and you won't really have to upgrade down the road. If not, then a smarty + gauges (fuel psi, tranny temp, egt).

Midnite

I agree with High Bid on the Superchip programmer.

The tranny temp gauge is a great idea, especially if you end up with some mild performance upgrades and still run the stock tranny. You can potentially get some really high (damaging) fluid temps pretty easily, especially if you give it lots of throttle in overdrive when the torque converter is unlocked. In OD with the torque converter locked up, you can also easily run into an expensive problem because the stock torque converter clutch can't hold much power. To be fair, it wasn't really designed to.

When I installed the tranny temp gauge in my '92, it was a real eye opener. I saw very quickly that some of my driving habits really made the tranny fluid temps shoot up quickly. So for me it was a huge value just having it for day to day driving.

Can anyone give me an explanation as to why when I tilt the steering wheel my headlights go off
