Maggie 2300 making 90+ kpa at idle whats wrong?
Car is making positive pressure on start up and when it idles its 90+ kpa, 408 with btr pds blower stage 3 cam, ls3 ported heads. Tuner thinks it might be a air leak somewhere past snout plenum area to lower manifold on maggie

Is the map calibrated correctly? I know when I switched from the stock map to the zl1 map It was reading boost at idle.

Map settings is correct as i did it myself with right specs, i can see the bypass moving back and forth til it idles out normal so its moving as should but i contacted magnuson supercharger and they told me to try certain things with the bypass valve and then email them back if thats fine, literally waiting to get off this cruise ship as i was gone 5 days so i will try that and if not then a vacuum leak somewhere
