What's the likely hood of a performance gain? My last dyno even with ported Tb's, upper, lower and 2.75" intakes at 7k you can start to see a fall on the red which is 5th gear. I could only imagine it getting worse. The blue 4th gear does seem to be rising though.
PS I'll admit something's not right with my parts. Tunes perfect but with all the custom parts I'm not doing what others do power wise.
