And who would I get the UpRev flash from? Or do I just have my tuner adjust the Osiris tune? Does GTM have to give you the UpRev file ? |

Call GTM and ask maybe it is something they can send to your tuner to put into your tune.

^ yeah really you don't need them for the tune since it is in the instructions you can have your tuner do it for you instead, so so long as there is a quick turnaround on the valve body it isn't the end of the world.

Ok...I had the VBU from GTM installed and everything good there. Had my tuner adjust my Uprev tune with the tables that Sam @GTM sent to me to have him adjust. So I get it on the road and it seems to shift a little better but not the drastic difference I was expecting. And to top it all off I lost my Syncro-rev (rev matching) completely!!!! WTF is that all about. On the downshift for those of us that are spirited drivers and like to use our paddle shifters since they are there..

all you did was the valvebody right? If you go in manual mode does your gear position indicator work right? The only things that should effect the synchro rev are if the gear position sensor is out, or if there is an issue with the speed signals or in uprev flash. Reflashing, resetting the ecu, maybe putting the stock tune back on just to shift it a couple times and see if synchro rev comes back would be a good couple of first steps. the ecu drops line pressure at low loads so it is not going to shift hard under full throttle. you could always have your tuner up the low load parts of the torque map if you want hard shifts all the time but you shouldn't need lightning shifts cruising around town.
Edit: are you getting any codes?

Just checked the fsm and the gear position and shaft speeds sensors are hooked up to the tcm on the valvebody could be that one was not plugged back in or something during the install as well, another thing to check. When you say swap your stock valvebody back in did you buy a core valvebody? you need to reuse your orignal TCM and gear position sensor from the car on the new valvebody to get everything to work so you must have swapped them, double check to make sure everything is hooked up right on the valve body and that you reused the original parts.
