Imo, the mid range still feels like you're making a hell of a lot of noise but not really going anywhere. Sorry to disappoint, it's probably more a fault of my own than of the mods or car. I don't think my butt dyno is sensitive enough.
I'm almost outa gas so I'm gonna give E85 a try tonight or tomorrow. I'm also wondering if new tires (still running stock and they tend to slip) or cleaning the 3 month old K&N drop in will help. I don't have the money for tires at the moment, but I'll clean the filter and try E85 and report back.
Regardless, I still don't regret it. The fat tail pipes, awesome race car sound, and eliminating that strange metallic buzzing noise above 4k rpm made it worthwhile anyway. Not to mention that now when someone says these cars are slow, at least I can say "well mine's got a lot of extra HP over stock". They don't need to know that I have a hard time noticing it 
Edit: I should point out that I already had drop in filter and stage 1 tune, and if memory serves from my reading, that accounts for almost half of the 22ish hp gain I was supposed to get from the mods. So I might only be looking at 10hp gain for the header and a couple more for the exhaust. |
1. KN filter doesnt need to be cleaned for 30k miles I believe. cleaning it will not help.
2. New tires will help the car in just about every aspect besides acceleration (unless you really are spinning wildly)
3. metallic noise you were hearing is from oft stage1 tunes on stock header, it is something with the variable valve timing.
4. the ecu needs time to settle after you reflash it. There is potentially more power there as it adapts. Give it a few days or at least 50 miles after you flash, if you haven't already. Also steve99's guides can show you how to treat your car optimally after reflashing, for quickest recalibration.
