Default Power loss at 5300 on dyno

I made 1 run at a dyno day last week and felt the car nose over at 5300 and then pick-up at 6000 then take a long time to redline at 6500.The rwt and rwhp reflect this in both their curves with losses of.I made 360/365.The roller coaster starts with a 15 hp loss at 5300 then up 15 hp at 5500 then a 25 hp loss at 5700 and then gets that back at 6000 then down again.I have never felt the car do this before or since.Does a dynomite dyno load the car more and make a problem more apparent? I have a B1 cam/918 springs/headers with less then a thousand miles.Any thoughts welcome.Thanks

Could be valve float caused by poor springs

Did you setup the spring pressures right? If there is not enough seat pressure you could be having some problems but I doubt thats the issue, the beehives are amazing springs and shouldnt be a issue at all to 7k if setup right.
