LOW dyno numbers with the stage kit...
Hey guys, I have been dynoing my car this month and I can't seem to get past 225hp and 209ft/lbs or torque with the stage 1, 2.9 pulley, and K&N CAI. Now I am getting a p0420 error once and a while which is "catalyst system efficiency below threshold (Bank1)". Do you guys think that is the reason for the low numbers? I dynod with the 3.15 and the max was the same with the 2.9. But, I did gain 15hp throughout the power band. I am just really frusturated that the car is putting out less hp with these mods than some stock cars.
Now I know that all dynos are different but that number seems a bit low. All of my pulls were in third. Any suggestions?????

Could that mean that your cat is clogged? Might explain why the extra air isn't giving you any power. Ya know, like it can't find it's way out the exhaust except at low rpm's.
