I still hit high 14’s on the dyno I believe. I don’t understand why an unknown dyno with unknown sensors and vacuum tube length is somehow more believable or comparable than the equipment virtually everyone here owns. Probably a 4 bar OMNI-Power sensor, a couple feet of tube, and ECUTEK software. These are all constants, so why not rely on them instead of insisting on boost numbers from a dyno?
