Well I have a dasmopar mapclamp not installed but my wideband reads --- on the rich side when accelerating. I'm thinking what if I install the clamp and clamp lightly like 4.3-4.4v. Im running a 20-21 spike falling to 13.I only want to clamp this much for safety because I want to see if my widebands reading right. Is this a good idea? About what should me afr's be expected to be. 80+degree weather here.
