I'm running andial IC, stock exhaust, stock internal, 1 bar spring. fuel enrichment kit. however my boost gauge is showing 0.9. It's a andial mechanical type gauge. not sure why. I was assuming the gauge is not 100% accurate. could this be a leak? in regards of the K27, i'm not sure whether it's a K27HF or not. All I know is a euro spec K27 from previous owner.
