box is in and operating, with the smarty and the tst adding pressure. truck is having traction problems.
I got on the freeway today and the truck got alittle sideways when it hit third gear, it was a little spooky.
the difference is noticable when adding pressure from the old tst box without. my butt-o-meter says so. the smoke is less black now also, more brown/gray.
the rail pressure gauge is a nice feature, but I do prefer analog gauges. I do like the auto cooldown compared having to push the button from the old tst.
I wish I could tell you more but I just put the box on today and just got to play with it for a few hours.
