Got two out of three Gauges going this Sunday. The boost wasn't that hard. Just had to be careful with casting as we drilled and taped. Thin wall. Under a hard excel I get about 11 psi which seems to be right where it should be.

The other one is the Pyro. What a pain in the Censored Read where everyone says to put it right before the turbo in that flat space in the manifold. They say to drop the wheel well and you can get right too it. Well after removing 15+ bolts I find that there is no way I'm going to drop the well without bending it big time or removing the whole fender. So after a little scratching of the head I decide to cheat. I drill a single hole through the well into the flat space. Tap using the hole and then install the probe. Once done I put a rubber plug to block the hole so that you don't even notice it.

Now once up to temp it's 150 or so at idle. Then cruising around the back roads its about at the 350 mark. When I step on it goes to 650 for a bit. Now on the highway at 65 it's around 500 to 550. Going up a step grade about a mile or so long accelerating it hit 850. Now this was just with the family in the truck and not towing.

Makes me wonder what type of numbers I'm going to see towing the travel trailer this weekend. 4.5 tons is sure to make a difference.

Last gauge to install is the trans. Looks to be easy as the wires and probe reach the drain plug. One of the three adapters look like it would fit. The plug has a large star fitting and I just didn't happen to have that size. So with a little luck and if no one says that I shouldn't use the plug that's where it will go this week. And finally I'll be done.:ro)

Your EGT numbers seem about 100 ~ 150 degrees cooler than what I'm seeing on mine. My probe is installed in the exhaust manifold on the driver's side, an inch or two before the connection to the crossover. But I just installed it last week, so I need more time with it.

Pulling my boat this weekend (97 YarCraft Michigan 19ft fiberglass w/ 150HP Mariner) I got the EGT's up to 1100 momentarily on a few steep pulls, when the 4l80e would downshift and boost would jump to 13~15psi. Can't recall exact EGT while cuising on flat grade with the boat in tow, but I think 600-800. Down hill slopes the EGT's would drop to 300~ish.

Curious about your tranny temp gauge and the temps it gives you. That's next on my list, but not sure if I'll ever get one.
