anyone emissions tested w/ a Supra AFM?
Do you have the results? I would really like to see a print out if anyone has one, or even simply to know if it passed? I'm wondering if it burns a little lean (high NOx) with the Supra AFM when in open loop (ie: WOT accleration). That might explain the increase in throttle-response (I'm not convinced it purely less intake restriction).
Bueller?

I'd look for high NOx in the readings. That would tell me I was burning hot, and most likely (considering it passes emissions now) could be attributed to a lean-burning condition caused by the Supra AFM.

But, I wouldn't change the timing until after the test, so both would b at 5* BTDC.
I don't have as easy access to a dyno, but there is a rolling road w/ emissions tester not far away for $40. BTW, how much does it usually cost to get your engine dyno'd
