Comptech SC: works properly at all altitudes?
Something I thought of recently....
does the Comptech SC unit (or the Vortech one, for that matter) react properly to changes in altitude / pressure? or is it only calibrated to work at a particular altitude. I'm a fan of twisty mountain roads, and it wouldn't do to have an SC'd S2000 not work well as altitudes rapidly change.
On a somewhat unrelated note....when you are at high rpm but not high throttle position, where does all the boosted air go? does it constantly get bled off in this situation?

It doesn't have any altitude compensation except that of the stock ECU (has baro sensor on the board).
When you have the throttle closed the vacuum in the intake is utilised to open the bypass valve. So the charge air feeds back into the intake tract before the compressor. I vented mine to air because it is hot.

I live at about 3500' altitude and I have gone from here up to around 8000 - 9000' in some of the mountain passes and down as low as sea level. The car seems to work just fine under all situations.
ps. The Vortech has a BOV that vents boosted air out of the intercooler.
