Cat bypass, Dansk 1 in- 2out sport muffler, Wong chip (I thought the car would run sweet after these simple, tasteful mods)
Now it runs a little different. It pops when it idles down after revving it, and on deceleration. When I drive it slow, the idle sticks at 2,200 rpms even after you push the clutch in. A quick rev with bring the idle back down perfectly. When I do this rev, a small puff of smoke comes from the tailpipe. The car does not smoke normally at idle or during acceleration. The car at times actually feels like it has less seat of the pants power to me. I would think these mods would be good for 15-20 hp. I should feel that. Either way, the car is simply not running right. I'm guessing AFRs are screwed up but shouldn't the Wong chip have taken care of that? The car has fresh plugs, cap and rotor, fuel filter, air filter. I'm not quite sure where to start. Thanks,

The first thing I would check is your idle contact and make sure it closes consistently. Also, the tailpipe smoke may be an indication of an over-rich mixture. These chips do not always pass smog due to rich mixture tuning causing many owners to resort to the original chip.
