help! boost questions to s4 junkies
<center><img src="http://pictureposter.audiworld.com/50502/a4_front_1.jpg"></center><p>a few questions to you guys about boost:
mods: x-chip, awe dps, borla exhaust, itg filter & no cats
what does your car boost from a standing start to the end of 2nd gear without launching?
im assuming the boost is load deppendent, that why im only boosting around 11-14psi from those gears if i wind out 1st (around 7k)?
at the highway i boost around 17-19psi,peaks at around 21-22 (i love the highway)?
where could i get the ko4 software alone for a good price(lower the better)?
is the a way to "fake" the load to the ecu to make it think its in a lot of load so i can be at 18 or so?
last but not least, what is the signal wire to the ecu for esp so i can send it 12vdc to make the ecu think the brake is on?
thankx for your time and help! chris

That sounds about right (more)...
I'm stage II with X-Chip and G2 exhaust. In the first two gears, my boost reaches 15 lbs at the most. You are correct in figuring that the requested boost is load dependant.
In 3rd or higher I reach sustained boost around 17 psi on 93 octane. For some reason, I don't get boost spikes.
