Your typical dyno will be done using the SAE correction factor. Expect your results to probably drop a lot using SAE. Hell, I dynoed 186whp SAE the other day and when converted to STD it was actually 201whp.

In conclusion, your dyno place just used a different correction factor that yields a higher horsepower number making you happy. Probably 90% of the dynographs on this site are done using the SAE correction. The stock ones that have 200whp or inflated numbers like yours are using a correction factor that will provide a higher horsepower number.
SAE numbers were: 190.7 whp & 138.5 ft/lbs
