How much vacuum are you seeing when the truck is idling? And how much boost are you seeing at WOT.

Im looking for trucks that are untuned.

At idle I see 8-10 under...driving i will get 1-3 under and WOT I see 12-14 typically.....I use a scangauge II though....

use it as a moderately reliable of information only....the codes to pull the boost and A/F ratios were provided by EngineerMike on this forum...

I see the same other than mine usually has more vacuum at idle, usually around 15 inhg at idle and between 2-6 depending on speed.

2011 EB bone stock Roush boost gauge between 15/18 in hg at idle depending on if its in gear or in park or neutral And up to 15lbs/s in at WOT for short burst [over boost] and a sharp drop while shifting [torque management]

I need to get a gauge. Does the Roush mechanical gauge light up in different colors depending on how it's wired?

The Roush will light red, white or blue. If you plan on install give consideration to the vent pod kit sold as an option. Also look on Ebay under boost gauges there are several options and price ranges there
