I'm not trying to question your dyno guy but Your base (stock) dyno seems kinda low, what rear gears do you have? I had a base (stock) dyno at 306 hp with Hemi and 3.92 gears and we had a day of 40% humidity, So on a more normal day I would of had higher HP... However your 2nd dyno (tuner) seemed a good number but I would hope that your truck isn't losing 152 hp once it leaves the motor... Normal conditions you should only lose 20 - 22% of your base motor HP...
