Glad you found a tune you like. I have an incoming sdrive40i, and really looking forward to the B58 motor. My last several 'fast' daily drivers were all TT v8s. I have a jb+ ready to install, just to check it out. Also have the jb4 ready to go as well. Considering pure turbo upgrade to shoot for closer to 550whp at some point, but that's TBD. I'm sure I'll do it, just for S&Gs.
