Should I gap the IT 20's at .35 with a 6 pound lower pulley and stock upper pulley?
See sigbrasil said:Anyone running these plugs here with about 12 -14 pounds of boost?
I see anywhere from 13-15psi when it's cold, so it should be about the same boost.brasil said:Sonic, I am going to be running a little less boost than a 2.80. WOuld you recommend I gap them at .35 instead of .38? Also, I was under the impression that the IT 22's are needed when running 7 -8 pounds of additional boost?
