Default Boost curves, just curious.

Hey guys I'm just curious to see what some other boost curves look like with different chips.

I'm running a k03 with a FMIC and a Dahlback stage one, looks something like this;
2PSI @ 1800 RPM
8PSI @ 2500 RPM
12PSI @ 3000 RPM
16 PSI @ 3500 RPM to 4500 RPM.
After that it slowly runs back down.

What are some other chips running?

GIAC is similar but it seems to push more agressivly spiking at 21 in my car and holding a constant 18

All K03 chips act in a similar way. APR would spike over 21psi hold around 16psi to arounf 4600rpm and fade quickly after 5000rpm as do all K03 chips.

If you want the boost to hold all the way to redline you need to upgade the turbo.

Here are 2 logs I took of my APR K04 setup... 3rd gear pull from 2000rpm to redline. It holds at 18psi and drops to 16psi.

i am going to have to log that on the vagcom. Mine will go into full boost at about 3600rpms(~18psi) and hold it until I bounce it off the rev limiter....lol

Yeah my GIAC spikes at 21+ and holds it nearly to the redline (i need to watch the road more and my boost gauge less)

I guess K03 setups work a bit differently between the B5 and B6

Everyone seems to be spiking at about 21 psi, I only get to barely 16 psi then it drops back down. Is something wrong with my setup or is that just how my chip is tuned?
