Just got done with the Dynojet Test SAE: 317 rwhp & 360 rwtq

I'm not sure why horsepower stays about the same and while torque went up about 40. An expert told me a tune will solve the low HP issue.

Using 20% lost at the wheels): 317rwhp/0.8=396hp & 360rwtq/0.8=450tq

MODS:
-AEM Intake
-Doug Thorley Shorty Headers
-Doug Thorley Catback w/ x-pipe,
-JBA High-Flow Cats
-No-tune

INFO:
-25,000 miles
-93 Octane
-L99 Automatic 6
-Open hood w/ fan
-weather: 72 F degree, 29 in-Hg, 47% Humidity

*UPDATED*
Here is a new result folks. I went to a Mustang Dynamometer this time. Another Dynojet machine is 1 hour away so that's not going to happen.

INFO: Open hood, no fan.

MAX:
331rwhp with WCF
346rwtq with WCF
AFR=14.8
timing=21

Compared with another L99 stock dyno result that was stored in the shop database.
MAX:
316rwhp with WCF
335rwtq with WCF
AFR=14.8

Gained: ~ 15rwhp & 11rwtq.
