I was riding around andgot to thinking about something that was told to me a couple months ago when I bolted up my Phat Shaft. I increased the boost screw on the wastegate to around 46-50psi as they instructed. Factory set at 40psi. 3-4psi increase with each 1/4 turn of set screw i cranked it in 1/2 turn.

I only saw and continue to see just 39psi on the Juice display. I was told this is the level set by the factory for the boost sensor to monitor and nothing more. Is there any program or higher rated sensor the dealer or I can install to get higher readings????????

Anyone else have this problem and solved it?

 

Mine will show 41-42psi during wot....

 

Yeh, thats the general consensus here!!! The factory sensor (which the Edge reads off of) is only going to read in the 40psi range. I think it has to do a bit with the BDPP boost fooling making the sensor read less than 40psi. But i was wondering if the dealer can reflash the ECM to read higher pressures without throwing a code? Especially now I'm well out of warranty?????

 

No...it is the limit of the factory MAP sensor. 40ish MAX. Get a mechanical to read true boost.

 

Man thats not what I wanted to hear. Couldn't you have just lied to me and said I could do a reflash????
