I have an 03 LE raptor with the following mods:
stage one hot cam
wiseco 11:1 Piston
K&N filter
airbox lid removed
and a dyno jet kit

I am about 900ft above sea level and I am now running the 146 and 148 jets..........
should I step up to the 148 and 150 jets?.........
I have heard that mikunis were better.........if so...what mikunis should I run with this set up?........

Thank you for you help

 

What pipe do you have now? Wshrdskin was using 148/150 in his with the same mods and an alba pipe.
I like the gytr kit with mikunis myself.
