I have my acctuator cranked! as tight as it will go,...and its up to 17# boost...which is where I want it however,...Should it be that tight?....Has anyone ever had to shorten the threaded rod? or do I maybe have to readjust somthing elese? I used to run at 20# boost w/ 110 octane...how am I gonna get higher boost for the track?..ps....no knock yet???
