is a tst the best box to start with when adding power. what stackes best with the tst

if you can maintain rail pressure then a bddl or smarty stacks great with a tst. just keep it on the lower settings. you can also add a little pressure with tthat stack but not too much. my 03 made 806hp with a smarty/tst/ez stack.

Personally, I think it is still the best foundation box to build on or just have the option to change everything and anything. I've had it from towing stock to drag racing with twin turbos at up to 90psi. Always upgradeable and mates well with the top downloaders and variable pressure boxes. Go for it, Kerry

So much versatility with the tst just wish they would hurry up and get something out for us late 06 and 07 guys.

smarty and mp8 much smoother than tst and on my 06 it made 50 more hp than the tst
