Hi James,
The core will be shipped out tomorrow! I just wanna say it's the best mod ever!!!! I have Hartge Ecu and a full turbo back exhaust, and it used to lose transaction all the time. Now, first gear, second gear, WOT no problem at all!! It still slips a little sometime, but nothing like it used to be, totally transformed the car! I'm very very happy!!!
