im finally getting some guages for my truck. wondering what the boost is for a 7.3 with just diablo sport programmer and intake. so i know what boost guage to get. never looked into boosting so im not too sure. thanks

You'd probably see around 22-27 psi I'd guess. 30 psi guage would do you fine. I opted for a 40 psi, just so I'd have it in the future for when I get into other upgrades.

Keep in mind, the stock turbo is out of it's map around I believe 28 psi. Meaning anything upwards of 27 psi it's just forcing hot air, and severely shortens the life of the turbo from what I've read.

Also, your results will vary depending on your elevation. Where do you live? I'm up in Utah, anywhere from 4-5,000 feet. If I stand on the pedal, I see 29 psi. When I went to Indiana awhile back, I could hit 36. Stock turbo. Ahh!!

i'd get a 40psi, thats just about a good range to have, and as said if you go over 30, no bueno, and over 40 is pushing your head studs... ha.

agreed good safe point. i've never past 1100. and that is if your thermocouple is in the up pipe or manifold. not the downpipe.

anybody have any feedback on the glow shift guages? tinted 7 color gauge series? just came across them never heard of them. or just stick with the auto meter?
