Spent a few hours at Diablo having Johan tune the TT Jeep. Problems with the boost controller and only able to get it to 17psi. Because we could not fix the boost controller and the next customer was waiting, we decided to make one more pull with a 100 shot and hit 1159HP at 5800RPM. The boost came on so fast he let out early so it could have been over 1200 since the TCM is set for 6400. There is a lot more left in her.
