Not reallysure what to tell you about the spots...
but as far as dyno numbers corksport is one of the top as far as gains
im really happy about the power & sound once it was installed , I never heard it prior to installing it
And I was very happy about how it sounded , especially how it sounds going 80mph on the fwy.
Sounds awsome in first gear , have no regrets buying it all.
got for $275 from NXTASI, really cool guy , we still talk & were planning to go out to Willow Springs race
track, hopfully take my car out to the track and really see what my car can do.
