Attention EDGE Insight Users

Over the past couple of days, with much research and experiments, I have come to a conclusion. The Edge Insight will not monitor boost correctly. I have both an analog boost gauge (tapped into the intake elbow) and an Edge Insight. When rolling into the throttle in 5th, I can peg my 35 PSI analog gauge but my Insight will read 27-29 PSI. Here is the reason:

When using an SCT w/ custom tunes, the custom tune has a built in 'boost fooler', in a way. It fools the computer into reading proper boost numbers so that it will not defuel. The stock tuning will defuel with any boost over 29 PSI. Since the Insight reads the parameters from the stock computer, it is reading the fooled reading. Many people with Insights have claimed there boost has topped out at 28-29 PSI, but that is incorrect.

Point in case, if you are concerned with reading your boost correctly, get an analog gauge and tap into your intake elbow.

I just thought I'd share that tid bit of info.

Very interesting. There was a guy in my tech school that had a cummins and had a 2 1/16" electronic boost gauge and a Quadzilla programer. Well he told me that he could make 50 psi of boost on his stock turbo no problem. I figured something along the lines of what you said were goin on. When I tried to tell him this...

Thats a triple kid and I gave up!

Thanks for the info/research

This also applies to the stock boost gauge on the '05+ MY trucks.

It seems to me that a person writing the tunes also has control over when and if to defuel your truck as well. When I go wide open throttle I only see 22 psi or so with Matt's tune. If I roll into the throttle in a higher gear with lower rpm it will build to 30 psi (this is on my stock boost gauge on my 05) Could it be that Ford is is only using a 2 bar map sensor?
