Default Re: Best upgrades for power xr8

Yeah im in the same boat as OP
I have 2010 boss290 and looking at cams and intake plenum.

All i can find is a yella terra side entry and a bpt front entry plenum with no reviews or power gains for either...and as for cams its either crow cam or herrod...again not much on gains and the opinions are varied
