lower your shift points .... 1-2 shift is the one that needs lowest setting, raise your rpm limit a hundred rpms a fuel cut during nitrous is dangerous

Your gonna want to get it to a good tuner to know current timing and shift points. Then will need to pull some timing in the tune or use a controller w/that 150 shot
