we get nerdy this week with Jamie at PEP performance tuning in California tunes our LTR450 CRF450 hybrid with a vortex ECU.
he talks about power under the curve, and most importantly response. What time to redline means for riding, and you can see how it made the quad 23% quicker! Crazy. Peak power isn't all that matters. Its rideable HP.
