Extreme loss of power at 7100 rpm. Help needed!

It would help if you data logged via UpRev so that you can determine what your MAF is reading , timing adjustments, as well as what your A/F ratio is

It would help if you data logged via UpRev so that you can determine what your MAF is reading , timing adjustments, as well as what your A/F ratio is reading. Two things come to mind; one that a coupling is leaking and a less restrictive exhaust or even a major exhaust leak could be the cause. But a 100 HP loss is staggering and I would expect something else related to the A/F ratio. First things is to datalog, as the data will always show the problem.
