re the GTM TT on 6 speed: It's mine and the TT's and everything else are running fine thank you. Kudos to John at Z1 for the install and tune. 8.8 PSi seems to be working out fine. In the spring I'll go for the JWT clutch/flywheel and we will see what 540 RWHP feels like. Drove car from Georgia to New Hampshire and it purred. :-)
