    Gen 3 SD my scanner won't read above 105kpa

    I have a 6.0 ly6 running a edelbrock e-force 2.3L on speed density, the biggest problem I have right now is that my vcm scanner wont read above 105kpa and i dont want to be lean at wide open throttle with 15psi of boost. What should I do????

    Remove the 1 bar map channel and replace it with the 3 bar MAP channel.

    You must also be running a 2 or 3 bar MAP to read that high too.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    I also did that i put it as a 2 bar because y have a 2.5 bar map, but on th very right side on the option says under parenthesis (pressure) if I use it under sensor it goes back to 1 bar won't read over 105kpa but if I put it on 2 bar (pressure) it won't read nothing just blank
