when you lock it up and get on it it shifts hard that normal? will that hurt any thing?

 

i would say that its actually better for the clutches because they are not slipping as much. but it might be harder on the rest of the drive components

 

on goerend's website it advises not to let the tranny shift while in lock up without billet shafts.

 

how u use yours 12valve801? our set up is close

 

you WILL break the stock input shaft by doing this! def dont shift with it on with the stock shafts

 

ya thats what i was worried about bc it shifts hard

 

Well as u can see from my sig I got my truck turned up pretty good on a stock tranny and I use the switch all the time for racing in town and haven't broke anything but it might be coming soon though but my truck shifts like new still.

 

what your egts and boost at with your truck 12valvecovery?

 

I have never got and higher than 12 and i smoked the crap out of this kid doing like 35 in forth gear yesterday and it was between 10&11

 

im at 30psi and my truck wont touch 1200* no matter how long i stay n the throttle.
