Disappointing dyno results

Does your guy really know how to run a dyno? What standards did he correct to? There are SO many variables here it's pathetic. I can run a dyno and make a stock 318 show 500HP. So there's THAT. lol
Hi Rob. He can run a dyno. Was trying to correct for A/F ratio. He only had a bigger carb than mine. Test results were not much different.
