Question about boost pressure.

I just finished my gauge install today (Dipricol Optix) and was wondering if 17 psi @ wot is ballpark. I plan on installing new boots when I do my foil delete and paint my pipes. Just wondering how far off i maybe and if I need to do the boots sooner. I had alot better fuel mileage before the guages but i usually don't speed everywhere to see if my gauges work. thanks

Without a tuner, that's about right. Could be a tad higher so check the boots.

Thats not bad without a tuner/chip. Keep doing what you are doing. Take it one step at a time. Keep adding mods, and you will hit more boost.

You think you don't have MPG right now. When you get the DP, you will not be able to help yourself.

About the best I have seen is 15-16 but I also still have stock exhaust. Looks normal

I have an early turd (smaller turbo), 6637 intake and 4" turbo back duals and can hit 22 PSI WOT empty. Towing I've hit up to 28 pulling a grade. Maybe it's my small, puny early turd turbo but I seem to be the exception rather than the rule.

I can only occassionly hit 15 lbs WOT but I got the Edge Evo and that I am told isn't a real gauge.

Gary, I hope your getting that reading just because the gauge is a POS, its either that or your leaking somewhere..

I get about 18-19 max with the red line unplugged in stock. I wouldn't worry about 17. Once you get tunes and start hitting 26-28, you'll know you're okay.
