we did a swap a 5.3/60e using the transfer case that was behind the 700r4. i hook the wire going to the vss. but it seems like im moving quite a bit before the mph shows us in hp tuners. and if i go WOT from a take off it bogs at like 2100 rpms and i have to lift a little then once the mph shows up it will go on down the road. i have disable all the TM stuff. wondering if the pulse is different and i need to change something in hp tuners.

 

The pulse is completely different and is converted in the DRAC module in your truck to send outputs to speedo, abs and cruise control. I believe you can tie into the one of the output sides of the drac module to get the pulse you are you looking for.
