I have tried searching and have not found anything that sounds quite like my issue. I have a single turbo 93 rx7 with a power fc. I have the redline set to 8200 and up until a few days ago it would reach it and bounce as normal. However, today I have noticed that after 7600 RPM power begins to drop and she will crawl to 8000 RPM and hold. No bouncing, no cutting, just steady 8000 until I release the throttle. It does this in multiple gears and will even do it if I rev it in neutral. The car still makes decent Vacuum and great power up to 7600 RPM before that drop off. Any suggestions? I am new to automotive electronics and still stumbling through this stuff.

 

maybe boost leak? may be better posting in the 3rd gen section.
