Re: Dual Quad tuning tips?
Normally if you increase the size of the MAB from the stock size the effect may not be what you think would happen . The main booster will start up sooner. AFR will richen in the low flow area ( such as cruise ) but will lean as approaching high flow area ( high speed/ wot ).
Also if you richen the idle mixture screws this will also effect the cruise AFR / richer. Or the opposite if you lean the idle mixture screws.

Re: Dual Quad tuning tips?
Update: Engine seems way happier on ported advance and the 14 degree bushing (10 degree was suggested, I started conservatively). Idle is more stable, return to idle is dead-on consistent (heaviest MSD springs). However, I will have to retune IFRs and then, slowly, make sure all else is in tune. Thank you for the help!
