this is actually the direct
link to the dyno results.
Anyway, i paid $250 from a company that no longer has a contract with DINAN so they were selling it to make room for different inventory. I figured i couldn't pass it up cuz it was so cheap (versus paying $650).
I haven't taken it out for a spin yet, i will post an update when i go to the store or something.
I asked DINAN a while back about that review and they said it does't usally add horsepower to the upper rpm range, but more towards the low and mid range. They said they're not sure why the guy LOST power. If anything he should have seen little to no difference in the upper rpms. The guy's use of an open-air intake could be the culprit. (these are not their exact words, but i talked to them over a year and a half ago and the original email is lost).
