Ok guys next weekend im dyno my truck, i was wondering if yall have any guesses to what i might put down, im going to try Smarty on #7 and #9 and see what it does.

 

Bump.........

 

Is the smarty the only big upgrade. I'd say your in the 400 to 440 range but I dont think that is will be on #8 or #9 more around the # 5 and #6

 

What do you have for Tranny mods? That will probably hold you back some.. I am still running on my stock tranny waiting for local shop to schedule me in to upgrade mine. I had installed a TransGo shift kit myself around 30k and still am afraid on standing on the throttle on higher settings.

I was at 400hp/780tq using TST on 4/4 with stock lift pump/ tranny and no smarty. Waiting on Billet DTT and SB62 before I make another trip to dyno.

I would agree you should be in the 400+ group. Good luck and don't kill that tranny if she is still stock..

 

ya the trans is still stock,im waiting for taxes so i can upgrade, put i heard the dyno isnt as hard on it as the street, but i could be wrong.

 

400 tops on the 04, SW9 is only 130hp.

 

No its not as hard BUT on stock stuff it will slip

 

No turbo, no stix, no pressure box, are you using a beta file at least?? I'll say 350 RWHP is realistic on sw 9. Try to get a beta file if you can, that is a few more HP.

Let us all know and good luck!

 

The dyno isn't that hard but if you are running any of the mod or wild torque versions it just comes on so quick you can slip the tranny real easy. There is no going back once you slip the tranny.. Only repairs will bring it back.. If you do dyno on the stock tranny with smarty I would start at the lower numbers and work up to the higher you will know when you should stop.

Or even better would be to install the lock up switch so the TC will stay locked up and in high gear? I had thought about doing this before my next dyno. I wanted this switch so that I could get truck in OD and then bring the RPM back down low without worrying about the truck downshifting when I stomp on it.

 

can u do the TC Lockup switch on an early 04?

 

WHat version Smarty? If not a beta, I'll say 385/780. If beta, Id say 430/870ish.

 

Its standard smart program, im kinda scared to run the beta with a stock transmission

 

my truck made 461rwhp on level 9. I had a fuel system, built trans, exhaust, cold air kit, stage 2 pump. that was it

 

I would say you might be ok if you keep it out of overdrive. I would think it will slip the stock converter maybe

 

ya i guess im best beat is to start with a lower number and work my way up to #9 if it will hold
