[s-cars] Re: short shifting to save first?

I guess we can all depend on you to give us what you think. First off my car 
runs just fine thank you very much. Going with a lighter and shorter BPV 
spring has done wonders to help with the boost surge which was only a minor 
nuisance very little of the time. Second I don't think I've lost any of the inherent 
ECU protection. I still get MAF cut-out if it reads too much airflow. And if 
it feels too much boost or detonation then it will retard my timing, something 
that I don't allow to happen. Top pressure boost controllers act like big WG 
springs. I don't hear a huge cry on your part for those that have turned down 
their WG springs to repent of their ways. As far as altitude correction that 
occurs quite naturally. As I drive down the moiuntain from Everboost, I will see 
an increase in boost level at lower altitudes. 24psi in Everboost at 8000ft 
and 26psi in Denver at 5400ft

As for the benefits they are many. I have 2 lower boost settings for 1st and 
2nd gear. 20psi for 1st and 24psi for 2nd. This allows me to run this turbo 
car as it is supposed to run without short shifting and leaving me well below 
the torque curve in that next gear. I also have a boost taper programmed in. The 
guys with regular RS2 sized tubos come about this naturally as those turbos 
start to run out of air above 5500rpm. My 57 trim T04E Garrett would give me 
28lbs of boost until redline. Since Dave Jones and I felt that it would be a 
good idea not to run the boost out like that we've got a taper that starts about 
6000rpm and falls off gently until redline. Here's a look at my most recent 
dyno run: http://pictureposter.audiworld.com/15038/hapmacdyno.jpg

You see the horsepower just falling off its high of 412 at 5800rpm. you also 
see that nice taper going down to 380hp at 6800rpm. The squiggly appearance of 
the line is due to the way the dyno samples its findings.

Another benefit is a major reduction in boost creep. The WG stays shut until 
you get to the desired boost level. We've mentioned the top pressure feature 
of the Apexi but it is also bottom pressurized and using these functions in 
tandem gives it a very precise management of boost. That brings up the final plus 
and that's spiking. With all WGFV controlled cars you will get spiking as 
that boost comes up to the desired level and then is exceeded. The Apexi AVCR and 
my HKS EVC just don't allow this to happen. The boost comes up and levels off 
at the desired boost.
