currently am running a 1.15 housing and has been ok for everyday driving(a little laggy). But i just hauled a 5th wheel 20,000lbs. gross up to dodgeville wis and i incured some surge and had a hard time accelerating below 2000+/- rpms. so i was wondering if choking my housing down to a 1.0 will help with my lag. any input is appreciated.
