The SSTT is supposed to make 40whp and 50wtorque on 93 octane.From what i have read so far i guess the JB+ should do about 10 and 10 extra on 93.Cant wait to see the final rsults and dynos.

Looks like JB3 (the lowest version on 91 octane) puts out about 340 whp, so the JB+ would be at approximately 330 whp?
