Most of the automatics that gave out were using the old BB flashing program which only allowed the DME to see 13psi. With MHD, the DME sees up to 21psi which is really helping with shifts. I've been having zero issues (knock on wood) since Pure stage 2. My buddy who has a single turbo N54 was previously using BB and would get DSC malfunctions regularly but is now using MHD and told me he has noticed a substantial difference in shifting and hasn't had any problems since. I would recommend upgrading your torque converter and valve body.
Thanks for the input! Curious I'm fbo and just running jb4. Can I just go ahead and run the MHD flash or do I need the bms backend flash first? Also, any suggestions as to where I could get the valve body and TC? I'm excited about these stage 2's. Hopefully they go into production soon
Use MHD to flash a BMS file (pump gas, race gas or E85). Once you flash one of these files you then need to change your JB4 steering wheel controls from 4/3 to 4/2 (4 being speedometer side. The 3 and 2 being the tachometer side). This changes this JB4 settings so that it now knows you are running a back end flash. You'll also want to make sure you're running the latest JB4 firmware. Once you make sure you are running the latest firmware, connect your JB4 to the JB4 interface (laptop or mobile device if you purchased the kit) and make sure your "duty bias" settings are at 0.

You can either order the tq converter/valve body from lvl 10 and have a local shop do the install or you can send your transmission to lvl 10 and let them do the install (not the cheapest route). I did hear of one other shop releasing these parts but I can't remember the name at the moment.

Pure stage 2 will be released any day now. You can place your order now which will beat a lot of people to it.
Awesome. Thanks for all the info. Who's the point of contact to place an order?
