It seems to be that the edge tops out at 25.6 psi on the boost. Is this off alittle? Should it be more? Or is this right. Cuz i'm considering buying a boost guage and gettin that as a back up. I am just curious?

stock map sensor is limited to 25.6 psi reading, boost will be higher than you are seeing on the edge. with my HJ i am seeing 34 psi at the manifold.

The edge limits the boost reading to prevent overboost codes. A backup boost gauge is a good idea if you are going to be playing with things...

I doubt that the Edge limits the boost reading. Otherwise it would be faily simple to think a number and display another. I think it's limited by the ECU capability of reading the boost since it's the source of the attitude number.

With my Juice 4.61 version my analog gauge reads 26. Later! Frank

since you didnt read this the first time i posted it here it is again.

Did you ever notice how some programs throw overboost codes? The Edge intercepts the reading and begins scaling it back at around 20 psi, to prevent overboost codes...That is why I have analog gauges also. Regardless of the factory sensor limits, the Edge reading is no longer useful above 20 psi...

i have the predator and an autometer boost gauge. highest i can get is like 23lbs. i think it should be higher. is something up?

get a bighead and adjust the boost by twisting (shortning the arm) when I ran the predetor I was getting 28to 29 all day with 7 twists
