I was wantin to find out more about the tst. I've heard quite a bit about but how much power does it add and does it add timing? what about fuel economy? thnx for any info

 

The TST is a fueling only box for this model truck. It is supposed to produce up to 120 hp. I got some of the best fuel mileage on the TST alone, without timing. The best I ever got was not with this box, but this box run by itself gave me the most consistent fuel mileage. I got the same no matter if it was on/off turned up and giving it all it had, towing, or driving it easy, it was always consistent within 1 mpg. I always calculate, too. I don't trust the overhead console with the digital readout. That's just my experience.

 

umm what in the world are you talking about.. what thing from TST.. its a company not just a thing

 

I think he was expecting the courtesy of common sense. He was definately referring to the PowerMax line which TST is most known for.

 

well i wasnt trying to be a jerk i just seriously didnt know what he was talking about

 

I run the TST comp and i really liked the box after i got the comp upgrade real strong box

 

I ran the TST comp version and had Bully Dog injectors on my 2000. I still miss that truck!!

 

THe TST really comes to life with larger injectors. I rarely use mine on the street anymore because of the cloud I leave behind. It does not ad any timing so it will allow you to run any option you want on the smarty if you stack them together.

 

Love the TST Comp stacked with the Smarty, an DDP150 stixs. I run the Smarty on SW3 for daily driving, and when I want to kick some **** I turn on the TST.

 

Me too! The the box is off most of the time. Need to go get-em , I flip the box on. It is usually set to #6.
Mine is upgraded to I think, 180 hp.
