I think the cat is most of whats hurting you. English Racing has data that the Gen2 5558 makes more power than the CEA (gen1 compressor) 5858.
Also, every MD is different. The car could very well be making 600whp+ on a dynojet. And then cat could be hurting you for ~10% power at that level.
And then VD data isn't always perfectly comparable to a real dyno.

I might just pick up a cheap $150 test pipe and see what happens. I'm actually surprised the cat is making a difference since it is rated for up to 850hp.

850hp out of a high strung 2.0L is much different than 850hp from something larger and not working as hard. I also wouldnt be surprised if a ~600-650whp Evo is 800 crank hp.

I didn't notice a hit with that GESI CAT, but I am only at 450whp. It IS rated for 850, but honestly it IS also a restriction of some sort compared to a HOLE.
Has was your AFR curve, and wasn't the E85 the crap from the NY ? Maybe it is something else....

No way am I believing a 600whp Evo has 200hp drivetrain loss. Sorry. With that logic, I was making 800hp before on a 5858. Come on, that's 25%. lmao. None of that computes with the hundreds of evos I have tuned over the years.

Bryan,
I just finished catching up on this thread, and apologies for hijacking, but are you still interested in selling?
I've tried reaching out via PM, but I don't know if you've received my messages.
