Hello -
Been fighting with a low RPM surge\buck while driving on 2010 ZR1 that only has headers. Car is running well in open loop tuning for MAF but as soon as we go back into closed loop the surging\bucking starts back up again.

Since the O2 sensors Have been moved further down stream is there a way to slow down the closed loop response like on older ECM's?
