Well I installed my 3 52mm greddy gauges tonight. Everything went pretty good, it wasn't as big as a job as a thought. Oil pressure gauge was easy, unscrewed the stock sender, the greddy one screwed right in. Turbo was almost too esay, cut the line, add the 3-way connector...done. Exhaust was a little more tricky. I didn't really like drilling/tapping in my manifold........but it worked out! Then just hook up power to the 3 and it was done. I'd say the hardest part of the install was running the wires through the firewall, tapping the exhaust, and getting the damn pillar to tighten down good enough not to move around. After dirving 2 blocks I love them. They look great and seem to be very accurate. I'm very pleased! I'd take a picture for you guys, but I have no where to post it anyway........so there isn't much of a point!
