Another Dyno Thread - Updated Numbers Coming

I will be getting my car dynoed again tomorrow at my family-ish's Mustang shop here in STL. $50 for 3 pulls, plus a small fee for AFR readings. I am interested in knowing my AFR even though my handheld will not let me lean out my AFR (only richen it).

Last October-ish, on the same dyno (Dynojet), my car put down 240whp/282wtq.

I have recently added Steeda Underdrive Pullies, a Canned 93 Octane SCT Tune, and I put my SR CAI back on since I painted it. I have modified my canned tune to advance the 4k-8k Spark advance a little more (now it's 23 degrees BTDC...started at 22). I'm debating on advancing it one more degree. From my research, I have read that our motors can handle 25-27BTDC above 4k on 93 but I will not push it. It is not pinging currently...

I am expecting 250whp/???wtq (a gain of 10). Dynoes tend to be heartbreakers so we will see if I even gained anything. I'll post pics of my sheet sometime next week.
