Hi!

I have figured out two options that seem ok if I am to upgrade my Promax 300 1999 model/2002 powerhead.

@ SVS Brucato Intake + Brucato High Flow Reed Plate + Tuner + modified ECU at Rapair Inc = 30 HP gain / approx. 300-400 rpms gain.

@ New MadEfi 3.0 intake + special reeds + tuner = 50 hp gain / approx. 600 rpms gain.

I would be very happy if any of you could let me know your thoughts re. their products & effect/gains. No point to invest
if I only gain 100 rpms .................

So - the big question - which should I choose??

Please help!
