When I get my car dynoed, the converter starts unlocking around 5000 rpm and the horsepower numbers drop off fast.I was told the computer is making it unlock. Also i was told the motor should make decent power to 6000-6500 rpm.Peak hp and torque is around 4700 rpm.by 6000 rpm it's 290 hp and335 trq..peak #'s are 420 hp and 461 trq.@4700rpm. this is a 2001 4.75 2v 6766 turbo.precision industry converter and stock cams.I have been to three tuners, no luck gettingthe numbers up. Any ideas out there?JOHN
