7.5k: OEM Slipped...
My Apologies for the misrepresented information. I was able to get the individual dynos and run through their respective numbers. OEM Max was: 492whp/378tq the GTR plenum 515whp/377tq.
I will clean up my posts prior and we can use this as a reference for the gtr plenum. Both cars were on pump gas and at 10PSI.

How are you coming up with these numbers? I mean just looking at the 7000 RPM Number, 360 TQ @ 7000 = 480 HP, not 490, and definitely not the 500 you are showing. And if the graph you are using clearly showed the 2 curves were shifted incorrectly horizontally, how do we know they weren't also shifted vertically? That'd be a really easy way to show an increase in power! Sorry but your numbers and methods are suspect. Different car, different day, different dyno? Im not sure. And then instead of using actual data, you overlaying photos to compare. It's just not working.
