First of all I was just joking, second of all, did you need to post 3 times consecutively?

No, Especially as a premie...

Q: I had my RB25det tuned on DD, got the dyno sheet, and the RPMs were way off. The shop said they only reved the motor to 72, where the soft limiter is set to, but the sheet had it revving up to 9000! I also read of another guy who had the same issue. Is this just laziness on the shop's part?

Sounds like they didn't set-up/isolate the pickup correctly for RPM. Easy to screw up on COP.
