Decent/cost effective gauges (FP/Boost/and possibly A/F)

Check out the innovate motorsports gauges, the MTX series. They are marine quality, not "water proof" but as good as your going to find for weather resistant. You can also add a pocketlogger to the gauges and log your afr and boost.
I just really like the looks of the Glowshifts, you don't think the flex seal will work?
