I can adj. ( low & high side ) 15lbs & above but not below .. currently i'm set at : gain > 1 , gain set: 3 , duty 35% = 17.5 & can push the duty % up to 50% = 20lbs ... i would like to get a low setting around 7-10 for easier driving -- i can even set the low at 1 , 1 & 1% = 15lbs ! we have checked all the connectors / lines & the installation appears by the book ... wondering if my apexi bovs' might have something to do w/ it ... upon initial installation of them they were too loose & i would stall at a light .. i cranked them down ( but not all the way ) & the stalling went away
