Alright guys I got the mbc boost gauge and air fuel in the car and she is running good. A few little problems I could use some help with. First off the aem uego reads 14.8 all the time no matter what. I'm gonna check the connections I just wasn't sure if this was a common problem that you guys have had. Second it throws two codes : random misfire and iat sensor high output. Just replaced the plugs too. Thanks for the help guys.

 

search around for the P0300 code...plenty of random misfire information on here...it's been discussed a million times

here is a video explaining the uego sensor...watch it

I'll watch the vid when I get off work but from what I read it sounds like the misfire is common in evos? It only burps and idle and I feel no mis what so ever in a pull or spool up

 

I watched the video. I didn't do that test yet however I read you can turn your key to the on position and the gauge should lean out to "---" if it's reading correct however mine stays at 14.8 for up to five minutes and still no movement. You think either a dud o2 sensor or bad connection between o2 and the gauge?

 

mine never stays constant it fluctuates between 14.8 and 15.2 even at idle...
