I made an intercooler/radiator sprayer out of garden fittings and used the rear windscreen sprayer pump, we'll see how much it helps (it cost me nothing but the scrap pieces in my garage of vac line and an old irrigation system).
I also wired in the factory OBD2 port to the Link canbus output, borrowed an elm327 bluetooth device and I now have a tablet dashboard working. All I need to do is mount the tablet.
