Is the core charge fully refundable if we do the "swap and send back the original after" option? Also, for HPDE / TT / Road-racey stuff (I'm probably one of the few doing that on a 7AT), does GTM have a recommended set of upgrades for the 7AT on an NA motor? The
VB upgrade is on my list, do any of the other bits you sell make sense as well? Basically my power hasn't increased much, I just need the thing to be a bit more bullet-proof under track abuse and firmer/faster shifts would be nice. Mine's used almost exclusively in M-mode.
