I have them gapped to .30 and they are brand New 6b11b Z1 said anywhere between .28 and .31 for 18 psi but i feel like its to close of a gap but never had a problem before. Also My BOVs are leaking even the new ones i bought I really dont have the money to be throwing around like this anymore. can you or anyone suggest a good cheaper BOV that doesnt leak? on another note my VTC and detonation sensor where crossed I figured it out when i had a friend tell me what color the wires were lol (colorblind)
