    Sorry for the stupid question but what is the logic behind cold air => use less boost?

    The air is more dense which means you need less boost pressure to obtain the same air mass compared to warmer weather

    Thats one theory but dont think it's accurate nor is the load based boost entirely accurate.

    "The ECU is load based, but boost targeted.

    So, if the load is not set high enough, it will not hit target boost. If the target boost is to low, it will over boost based on load. " (per Tork)
    Kia lowers the boost in cold weather to avoid overboost (per Lap3).

    Terry just agreed the max stock boost is 14 but here is my stock dyno showing 13.87 psi. Wasn't able to find Locke's boost gauge pic showing 14 psi.
    I guess the jb4 log is wrong.

    Does it really matter what the stock psi is ? Is it that big of a deal? I mean it can be anywhere from 10-14 psi depending on conditions. What is the point of the argument to be made? Everyone is going back and forward on stock psi.

    Most I seen a JB4 is like 18 psi. Ecu psi the most I seen is 12 I believe. Again seems like a redundant argument.

    If the point is that the JB4 is wrong then state that with with evidence or whatever the point that is trying to be made.

    I have a physical boost gauge. I can test this When I have time since I have a JB4 and AWD stinger. But it seems like I would be wasting my time to be honest, hence the reason I have not done it yet.

    A physical boost gauge and a electronic sensor might not be exact. Not just in Stinger but any car.

    Not really that important but Stungbluegt2 is trying to claim tune superiority since JB4 runs lower boost which isn't the case. That's all.

    My 13.87 PSI was at 50 foot elevation in a 70 degree room so not extreme conditions.
    I think your load based explanation is also over simplified as there are many ECU tables for air charge that play a major factor. The max air charge converted to PSI from hectopascal is 16.6 PSI but don't think anyone has seen that stock since this table nor a torque target ist the only factor. But I think you and John have had these pissing matches before.
    Bottom line 14 PSI is commonly seen in normal conditions on multiple cars with multiple different gauges but rarely seen in a jb4 log file. If map 2 runs 18 PSI rather than 16 PSI and WMI is running 22 PSI rather than 20 PSI people should know that.

    Good to see you updated the firmware.
    I was in RWD mode on the dyno. But Locke has an AWD and hit his 14 PSI on the road with his gauge. He does drive it in RWD mode so I guess we may be able to get him to test that theory for science. @Michael Locke ? I haven't seen him on the forums much lately....
    That was just one table I was referencing so not implying stock would/ could hit 16 PSI. I just don't know.

    The only I care about the V10 firmware.
    so for the new v10 firmware update we will be getting less boost? Or just reading less boost?

    Not sure if I want to update now lol.

    And if I read your comment correctly the V10 will show slightly higher boost as you didn't want customers saying they were getting lower boost than the log showed.
