I dynoed the SS today. The best pass was 331hp and 344tq. After a stock pass I tried to take the air filter housing off and run it with only the MAF. It didn't like that at all. It dropped about 20hp. Then I tried with just the resonator on and it didn't like that either. I figured it would make it run leaner but it didn't. Both changes made it run richer. I can see where there is a lot of room for tuning. Mine was pretty rich. It was around 11.6 most of the run with a spike up to 12.3 between 5,000 and 5,250 rpm's then back down in the 11's.
