Has anyone used the Pulse Charger yet . What was the recommended jetting ok?

Posted by: Kennethyfz450

I have..

so far the jetting seems good... why you ask?

Because I tested it on a 450R on a dyno with the recommended jetting and it was VERY LEAN almost 16 A/F and made less power. I had to jet from a 165 to a 185 to make the best power .
