New Pilot ??? SPARKS

[Ryan300exRider]

I just got my Sparks x-4 system for my 300ex and i have a question. I have a fully open airbox with k&n airfilter and now the full system....When i called sparks to order it the guy said that all i need to run is a new 152 main jet and nothing else....My question is do i need to buy a new pilot jet or move the needle up because i dont wanna lose preformance ????????

i would think so. give it a shot. move the clip dowm to the bottom. I did that when i got my pipe and filter, and with jetting has me at some nice hp, but this is with my 300 w/ a FMF megamax.
