I wouldn't think a clogged fuel filter would cause MORE smoke...probably less smoke since smoke is more fuel than needed (initially anyways). More smoke could be from loss in boostdue to bad air filter and turbo/innercooler performance/condition. So you have a PCM with a tow tune and a chip?
I would have the pcm in a "stock" format but to run single shot injectors. Then have the chip for tunes. That way to pass smog test, just pull the chip. I know of some people that get better smog results with some tunes (they knew the shop owner and wanted to try it out) but a lot of those shops won't touch it of it has a chip. That's my thinking anyways....
