Idle air distribution is sparse (<1 g/s per cylinder) and quite fickle, and you are running those phenolic spacers. Not saying it's doing anything, but it is another random element in your intake tract.

that was with 10 gallons 100 oct Trick from a pump and a gallon or two of 92 oct. about 65 degrees ambient temps.

only race gas log i have handy as i got a new laptop and i havent used racegas at all since being in california. it does do a decent job showing the timing and the MAF #s i mentioned. 23-25 psi IIRC.

the log is actually in there twice

shimon could knock it out for you in less than an hour i bet, or you could even DIY.

local guy (A box, bosch sensor) runs more air than me even with 90mm MAF, similar boost. His airflow went from 310 g/s on 83mm to 280 g/s on 90mm, though. The whole conversion factor thing doesn't really work because it depends so much on how the intake/airbox is fit to the MAF. Also, I don't think you can really compare Bosch and Hitachi since they max in different places which would indicate that a certain voltage doesn't translate to the same g/s on both setups. Did I mention that this other local flowing so much more air is just about the same speed as me?

I'm pretty comfortable with my readings, seen enough logs to know there are cars on same intake/MAF setup seeing proportionatal boost/airflow.

Thanks for your concern, though.
