hooked up my saber on the weekend - piss easy to do (partly because I already fed my wires through the other week when i tried to hook up what i found out was a broken gauge...)
What i did have to do though was cut some pieces of the tubing supplied with the gauge and fit them over the stock air feed thingo on each side of the cut i made for my gauge's boost sensor, because my tee piece was too big to fit into it. I wanted to replace the whole tube with the stuff supplied with the guage, but the inside diameter was too big to fit tightly to the plenum ... that probably doesn't make a lot of sense, but i'll take some pics tomorrow.
anyhow, gauge is sweet, pretty much matches the stock one, but the extra increments make reading boost a lot more accurate! turns out i max out at about 5psi in 1st and 2nd then up to 8psi in 3rd 4th and 5th?? this is with a bleed type boost controller currently set just above it's minimum (still haven't got my intercooler yet and was waiting til i had a better boost gauge and fmic before i up it)
