Dear ST,

2010 HD FLHTCU 96 with 510 S&S Cams, K&N Hi-Flo, V&H X-Pipe, and of course the ST slips-ons + just installed ThunderMax.

Struggling a bit with the ThunderMax, as it a closed-loop auto tuner. Getting much higher AFR on the rear cylinder than front.

What would you suggest for number of plates, L/R side?

Thank you very much!
