Arrow Running Lean!

Got my car dynoed today, and can't say I was too happy with the results. My car only made 362RWHP and 367RWTQ with MAC headers ORY, magnaflow catback, TR 224 cam and stock 241 heads through an M6. The problem was in the A/F.......it was 13.8:1
I know with these mods I should be much higher up in HP and TQ right? The car was tuned about 2 weeks ago, but apparently it needs more fuel. What is the right air /fuel ratio for cammed LS1's? What kind of gains can I expect once the car is running right?
Any opinions/suggestions would be much appreciated

I don't think you will see some magical 15-20rwhp gain. It's not like your THAT lean. Like mentioned above you should look at your KR in order to get an idea of what you have left in it.
