Chip upgrade for plenum?
If adding the RSS plenum is increasing flow, wouldn't this be a parameter that a software upgrade could maximize? Are the chip guys working on it?
Intake+Plenum+Headers+exhaust+the chip that ties it all together=?HP

Without a chip, the plenum should trick the ECU into thinking it is closer to sea level than it is because of the higher airflow and density. The chip would tweek the values even more at the expense of emissons. It does also raise the redline and remap the throttle (which is the best reason to do it)

GIAC has a program written especially for a 996 with an EVOMS CAI, this will take advantage of the additional flow from your plenum.

My rev's climb so fast I hit cutoff in just about every gear every time I drive, and I've had 20,000 miles of trouble free driving.

that is not good.....my 99 runs better with EVOMS and plenum than stock. I considered a sw flash but I do not see much benefit to it. Seeing you tried the GIAC and lost performance.....thanks for saving me money.

no David... that's not what I'm saying.... I had the GIAC FLASH + EVOMS and the culprit here was the EVOMS cold air kit... when I went back to my K&N panel filter and stock housing the car ran much better... the GIAC flash is a worth while upgrade that is for sure... especially on a 99.... and the plenum has had tons of +ve feedback..... but the EVOMS cold air kit... no way; not on my car.
get the GIAC Flash.. and get rid of your EVOMS.
