Re: check valves? what kind?
 

im using a old safc that can only remove 30% of fuel from my 450cc (i know im still running uber rich ) But .. when i hit 10 psi my map sensor see boost , do you think adding 1 or 2 check valves using a afc setup would work ?

Uberdata and Wideband kit is on its way alrdy. sould have it in 2 weeks or so it's only to see if i can fix these problem before switching management ...
