Our cars, not so much but as everyone says, the manifold is why you're dropping off because thats the characteristics the manifold has. Now if you're making 5hp less then your baseline.....then you may want to start checkin things like spark plugs (which shouldnt be a problem if your under 75k miles) or in a bad case scenario, cylinder compression.

to put it simple, you're digging for an answer you want because you don't like the answer you're getting even with multiple people telling you what it is. Dont know where else to go from there.

its not that im digging for a certain answer, its that i know it isnt the manifold because the manifold on the other dynos ive seen it drops 3-5whp in the last 200ish rpm..my car makes good power til 6900-7000.stops making power(plateaus) til 7800-7900 then dips down...the dip isnt the issue..im trying to figure out whats causing the plateau from 7-7800rpm..which in any z i havent seen that happen lol...i guess its better to understand when i put up the dyno sheet...let me email it to myself and upload it
