just wonderin when u stack the two what power levels do u have to run like the smarty can u run any levels only with added timing or without?? and what ones do u think are the smokyest

They're a couple of the the best stacks on the market. The Smarty is a timing/duration with a little pressure downloader and the TST is a fueling/pressure box which is hard wired.

The Smarty does it's fueling down low and then the TST takes over the fuel up high. The TST is very adjustable to where you can turn on or off timing, increase fueling, adjustable torque management , adjustable rail pressure and it also has a turbo timer. Probably does a few other things too.

Some of you guys here are wondering why the Smarty has the power it does compared to boxes you already have.... it's because the torque management is removed for one and some sweet programming for another. The removed TQ management is mostly what you feel in the seat of your pants

Just remember.... you CAN NOT run a TST on a CTD with a build date of 6/06 of after, you will melt a piston ! plus, they wouldn't sell you one anyway if you told them that's the year you have.

 

What's the difference of those built after 6/06? Different material composition used for the pistons?

 

the ECM's changed after that date. It's still a CAN-bus but, many of the signals are sent via data instead of voltage. TST never got the newer computers figured out on the box so they took it off the market for those buoild dates until they get it figured out. Word is though... it's not gonna happen. They've moved on to the 6.7's

 

so when using these together doHAVE to use to timing on the smarty?

No, but if you want to use the TST's timing, you'll need to run the smarty on even numbered levels ( no added timing ). If you use the smarties timing ( odd numbered levels ) you'll want to keep the TST's timing off or with not a lot added.

 

Ty. . .one thing I noticed is his truck is a 99. . .VP44 pump. smarty and TST run differently on these engines than the HPCR's we have.

the concept is the same, load smarty to give you the power boost, then use TST to fine tune it in.

 

correct you are sir... I didn't, but should have notice that. I suppose he can run loads of timing then from what I know about the 2nd gens.
