Its dark now. I'm planning on doing the same bulb install, and look forward to your comments.

I guess you weren't around in the 1970s, when new stringent federal emissions laws took effect. Cars of that era ran much cleaner than earlier model years, but ran poorly as a consequence of being cleaner.

It doesn't, but tuning for ultra low emissions may result in "driveability" shortcomings, such as stuttering/hesitation.

I suspect that Subaru will never have a total solution to this problem because they are restrained by federal emission laws, and any reflash of the ECU cannot result in an increase of exhaust emissions. On the other hand, aftermarket tuners do not have to comply with emissions laws, and have far greater latitude than Subaru when it comes to ECU reprogramming. Either that, or the Subaru engine management engineers are not very smart.

Didn't Vishnu Tuning resolve this stuttering issue months ago? As I recall, they changed the calibration on the throttle-by-wire and on closed/open loop switch over parameters, resulting in elimination of stutter.
