Dont give the dealer any more $$$ than those crooks deserve. It took me several attepts to reset the ECU, There was one part of the sequence i wasn't executing properly, but it's less hassle to practice than take it to the shop.

I'm running a K&N drop in filter, test pipes, and a y-pipe and I haven't experienced any CEL's. However, my butt dyno is telling me that the car felt quicker when it was totally stock. Should I reset the ECU?

opening up your exhaust with a ypipe and testpipes will lose some low end torque which is why you probably feel it is slower than stock. in all reality, your top end is greatly increased and your 1/4 mile time shouldnt be hurt at all, and possible helped by your upgrades.

Okay, so I'm not losing my mind... Should I just leave the ECU alone for now?

resetting it wouldnt hurt. If you didnt reset it after the mods it might be a good idea! people claim the ecu learns things over time, but you can never be too sure. Try resetting it, I know my car always seems to run a bit smoother after a few hours after resetting the ecu.
