Would appreciate a log check. Second time owning a JB4 for my car, but this time around it doesn't feel as smooth and feels rough (ever so slightly) at partial throttle. The car feels better with more throttle applied then less. Log is done on Map1, 91 oct(with a gallon of e85 - was previously testing if the roughness was octane related) vehicle is stock with new Denso 5346 IKH24 plugs.
