Well I give up! This Thumpr cam is nothing but crap. Checked for vacuum leaks even hooked the Guage to the dipstick tube and no leaks. Played with my idle timing and af mixture which do change so I know it's on the idle circuit. I have spent too much time just on this crap. I'm done, going with a Lunati cam like I should of from the beginning and get the bark with the bite.
