i bumped my plug gap 1 last time feels really solid, bumped it up to .45 took it on a few highway runs and it feels really solid and smoothe. dont think i will go any larger tho
also i must say that the idle and response is from what i feel much greater with the larger gap than from comparing the same tune/psi to the larger gap the throttle response feels stronger and more instant on the larger gap....also with larger gaps the fuel is burnt more cleaner....i think for kicks i am going to index my plugs to see how that works out, thew whole indexing thing makes sense to me having ths park exposed to the fuel more directly, weather or not there is a differnece i donno, but worth a try no harm.
i will say the only draw bakc from having .40/.45 is that the start ups are slightly harder have to give it slight throttle, however i could go into the aem and adjust the injector crank tables to correct it... but i dont think that is much of a drawback from the benifits i personally think that the larger gap is making but thats just me
