Smarty 4.2/tst stack

I finally got around to hooking my tst back up today. Its the cr47 box. Ill be sending it in soon for upgrade to the r49 box. But Im currently running 4.2 beta on my truck. Well I had forgot I had it on sw9 and I turned the tst on when I got done and put it on both 2-0 and 3-0 and got on it.. The truck ran great and made no funny noises or unusual things.. Did I hurt anything running the smarty on timing and tst timing also since the r47 doesn't have adjustable timing??? I turned the tst off and its running fine no problems. Funny thing is. WHen you turn both tq and hp settins on zero on tst its suppose to be off right?? Well with it off and sw9 loaded it still feels stronger even with the tst off.. Any ideas??

You probably didn't hurt it .. Yet.. However a lot of timing can and will kill your headgasket. I'd avoid it if you can help it.

I dyno'd my truck with 4.2 on 8 And TST 3-0 and made 523/934

I was told to keep going up until HP drops and then go back 1 level.
It was a Dyno day and only got 3 passes
4.2 8 and TST 1-0 then 2-0 then 3-0

Wish I had the chance to try andding the TQ side to see what 3-1 or 4-1 might of done?

Even a pass with just 4.2 on 9 and TST off would have been nice just to know.. My dyno day was before Revo/TNT came out and I may schedule a day to go back and make additional runs but want to wait until Sticks and CP3 go in.. Maybe even a CAM/springs 1st...

4.2 is definately a smokey recipe compared to the 4.4 I was using as my daily driver program and loved it. I almost have the TNT/Revo working similar to how 4.4 felt and it does feel stonger to me SOTP.

Good Luck and be careful..

did you have your turbo installed on the dyno? Im not sure what mine is making. I have everything but turbo and my fuel system not installed yet.. It pulls pretty dang hard on sw8 and I have gone as high at tst 4-0, then it kinda feels like Im running out of fuel.. And gets toasty fast!! Didn't really mess with the tq settings yet.. I am pulling my rail down on the bottom end but maxs out about 26,300k with it stacked..

Yes I had Turbo.. I have many people say I am around what I should expect for HP with Stock CP3 and Sticks.

Did not have Smarty for long before Turbo and Tranny went on. Never dyno'd with Smarty on stock turbo.

Im still on stock turbo and fuel.. I got some fuel things on order that will be here very shortly!! I know from a dead stop its laggy for a second with my converter and tst on 3-0 and smarty on 8 and once it lights it takes off quick!! Pulls hard. I can only run it to 70mph though because it gets to hot!! I know I ran just smarty on 8 by itself and marked the distance it took my to get to 70mph and turned around and did it again this time with tst on 3-0 and I got to 70mph about 60 yards away from where smarty alone took. All in all I like it. I need more air and fuel def. Can tell where the truck runs low on fuel. Sendin my tst in to update to the r49 also
