Stock boost levels usually peak between 15-16psi, depending on ambient temperatures (and other factors). I know lap3 pro tuner peaks around 20psi on 93 octane (I believe stock ecu limits boost at 21psi). I imagine jb4 is somewhere in that area depending on your chosen map.
Thank you so much modjack! Time for a drive
Switch back to the previous version and see if it stops before doing anything else.
No actually I had a shop do the install. I live in an apartment so there was no way I could even attempt it. Also the shop did it for very cheap considering i promised him i have about 4 more N's coming to do the install and just spreading the word around for him!
I managed to find the problem. It was the fan control module some how water got in? There is a big plug underneath the intake where you would hook up a velosa tech big mouth ( the part that would feed air to the stock airbox ) very strange I've never washed the engine ( like spaying it with water) but some how water made its way in to this big plug i unplugged it cleaned and dried it and everything is working fine. It has nothing to do with the JB4 update just a Weird coincidence.
Iver been told by burger motor sports that you can run 91 on map 2 but it must contain ethanol.. I personally wouldn’t run it, but it wouldn’t hurt to try it out, log it, and send a log in to BMS.
Yeah, but not everyone is in the US 😂
Are you at sea level?
I'm usually (as in 99+% of the time) between 4400 and 6000 ft.
Sounds like it is reading low. WOT peak is usually around 15-17 psi. Is that the JB4 scale or the one on the gauge cluster?
