What is it? I was reading a thread about owners having problems with it. What kind of problems?

 

Do a search.
TST makes performance boxes for our trucks.
Some years add fuel others add fuel and timing.
Fill out your profile.

 

Wow, ur a lil demanding...do this do that...

 

There is a lot of info if you want to do a little reading , by searching.
I asked for your info on your truck because the boxes to add power with are different for each generation of truck.
Sorry if you take offense.
Would it have been better for me to NOT respond?

 

You boys play nice!!!

j-fox is right by the way. It's a lot easier to help if we know what you are driving. Different year trucks have different products that help them make power. A TST box for a 99 CTD will be completely different than one for an 04 CTD. The search function is just a way to keep us from having to answer the same question a thousand times.. On the other hand, I think you need more letters than TST to do a search so you may want to go to the 2nd or 3rd gen perf sections (depending on what you drive) and post your question there or just start going backwards through the posts to see if you find your answers..

 

and pre '98s have no use for a box at all

 

Well thanks for the responses guys! I had no clue what the box was when I was looking. So that might be why my question was so hard to answer. New to diesels. Anyway I will make sure and just use the search button when I have questions...btw I don't own a diesel yet. Still driving a gasser... I want to learn more before making a choice about what to buy.

 

Well....if you want power, mileage, and a real truck. Then get a diesel. won't say what brand (Dodge ) they are the best way to go.
