Well shoot, I'll install an air intake temp gauge too! [laugh] I've got 4 or 5 gauges laying around as well as a triple dash pod. Might as well use them if I could. So what's the point behind an air intake temp gauge? It seems like the gauge needle won't move too much.

Yeah, that's what I was thinking. It's just too fine. The filter might help but eventually something will still clog.

I've run a back pressure guage for about 6 years now.

It's plumbed with a kit from BD Power. Basically all it is is a 12 inch stainless steel line off the exhaust brake elbow then transitions into standard 1/8 inch nylon boost line up to the guage. BD does use a damper/filter of some sort on the end of the stainless line. It hasn't clogged yet in 6 years and I use the exhaust brake everyday.

You might think it's a waste of a guage but until you run one, you won't really realize just how useful it is. Obviously it shows your exhaust braking pressure but it also shows your exhaust system restriction when your really hammering on it. I had a muffler collapse on me and it showed it right away. I like it for the fact that it just monitors your pressure when your really using the exhaust brake. 40 psi on the guage is a lot of braking power!! 50 will lock the tires up on wet pavement. It just gives you an good indication of the braking power at different speeds and in different gears.

Actually I do have a leak but it's not the gauge. It's the wastegate spacer between the manifold and the top turbo. haha I think I used like 3' of copper (coiled it's only about 1') then plastic the rest of the way. The plastic turned black in the first day but the gauge works fine.

Well my backpressure is consistent with my boost (1:1) until about 70psi of boost, then it spikes and pegs the 100psi gauge when the boost gets above 80. So it helps me set my external wastegate. If your not running much over a stock turbo it's probably not needed but it's a good idea if your doing many mods.

Just put a tiny little DPF on it, LOL. j/k
