Since there's already a thread on the ProSport, I'll just chime in here..
I'm done installing a ProSport Premium Gauge myself on my Speed3 but I do have an issue with it already.. what's the reading supposed to be when the Acc. is on? Shouldn't it be set to 0? i.e. no vacuum/no boost. Mine reads -2 :wtf: What about you guys? Is there a way to adjust the needle to where it should be?
Other than that, the amber lighting is a perfect match with the rest of the cluster and I registered a peak boost around 16 PSI which tells me the install is fine.
