Hey DD, Fair enough. Car feels a bit better at times, but it's probably based more on temp than anything else. I'm not noticing any corralation between the gauge issues & performance. Any performance issues I'm putting down to heat & no spool/wrong gear Idles high at times. I'm putting it down to a slightly low battery or something of a like. Gauge is stock on the F6. No mods to the car at all restart the car & the gauge might still not be working, next day it'll be working fine. There's also the issues where it's not reading an absolute zero value durring idle/full vac. Tap the gauge pod hard & it sort of rights itself. I'm starting to lean towards a faulty gauge?
