Where is it located?
Where is it located?
I have that hose sitting in the back of my car since I recently installed a MBC ... I should go take a look at it to confirm.

If it's just your gauge and your using the stock one, you should get an aftermarket boost gauge, they are more accurate. I do think a MBC will help, but I still am not sure why you are down on power so much when your boost is spiking to 23-24psi. You should be at 260-265WHP. Can you post your graph?

who cares what the dyno numbers read..its all subjective to the dyno. Its the increase from a baseline that you need to worry about.
Just for comparison.....I threw down 248whp on a dyno dynamics (intake and CBE)and then 227whp (intake and CBE) on a mustang dyno....although the local dyno here in vegas seems to have gone out of business.....so now I cant retest.....

I hate to really comment on other people's plots (OPP? ) without knowing the whole story, but something is definitely up. Spoolup seems delayed compared to a properly working car and the hp dies up top prematurely when it should continue upward.
On those two points, compare to this graph, which is a bone stock IX with only MBC + flash (stock exhaust!). This is a high reading Mustang dyno, so the absolute numbers aren't significant, but the shape of the curves are, as well as the fact that that it gained ~50whp/50wtq over baseline with just the flash and MBC:
Mike obviously knows what he's talking about, maybe he's not off base regarding the cat failure or some other similar problem with the stock system? It definitely doesn't look right ...
edit: i know this is a IX comparing to an VIII, but still the points are valid i think ... it's definitely choked up top and spoolup seems slower than other VIIIs as well

throw in a ebc or mbc and try a different dyno. that should show a difference. also i was once at a dyno here in south florida and for some reason all the cars especially a friends turboed hatch recieved very low numbers. the up coming week i was told this place was being sued for "rigging" their dyno to show low numbers so the people dynoing their would end up paying for a dnyo tune and other work. im not saying this is the case for you but you never know.

And boost is boost in my book. Yes the MBC might possibly allow for quicker spool and less boost taper, but if the reported boost levels are accurate, it shouldn't matter in terms of power output if that boost is controlled with MBC/EBC/ECU ...

Hmm... I've got close to the same mods as you. It does seem a bit short. I have Megan TBe w/ Helix HFC. HKS RS Intake, and a P2 flash. This is from the Gruppe-S Dyno. According to Gruppe-S, a stock 05 Evo will dyno between 210-215hp for reference.
