Those of you running OBA. How do you keep a high idle when using air? I've just finished my set up and it seems to need around 1500rpm to keep a constant pressure when using air tools etc. Does any one use high idle solonoids? Choke cables? Pictures and ideas please! This is on a TBI and I've considered using the A/C command high idle but I don't think it's enough (although I could programme it higher but then I'd also have a too high idle when driving with A/C on). Any thoughts?
