    How much peak boost are you getting with cobb stage 2+?

    I did some live data loging and saw on the ap it was getting a peak boost of 21.7to 21.5 pull after pull.Are you people getting the same peak numbers??

    thats probably the peak while shifting. not sustained. Is basically the result of the throttle closing. The boost is capped to 18.5 sustained.

    Does that closure happen even just letting off the throttle with out shifting ?When I was running the st map,peak boost I saw was 18.6 to 19.1 . Getting this with the linear map and new firmware added .By the way didn't like the st map car felt it would die off fast and not as a smooth with some surging .

    I've seen 19.1 psi manifold pressure measured by my P3 Gauge with dedicated boost sensor.
    From all the things I've lost,
    I miss my mind the most!
