I have a Trailkblazer 250 (year 2000) I plan on putting a RCR stage 1 kit on it with a midrange pipe...how much of a HP gain will I have at the lowend(3500-4250 RPMs lets say), midrange(4250-5250 RPMs), and topend(5250+ RPMs)?

THE RPM RANGES ARE ESTAMATES I CAME UP WITH FROM GRAPHS, SO IT REALLY DOESNT HAVE TO BE EXACT.

I know a stock trailblazer(like mine) puts out:

lowend: 10-13 HP
Midrange: 13-18 HP
topend: 18-22 HP

So back to the question: How mcuh will these numbers increase with a RCR stage 1 kit with a midrange pipe?

 

I would say about 25-28 hp , i might be wrong... But any extra hp on the tb helps a lot...
