Default giac boost vs. apr boost?

Hey I was wondering what are the boost differences between apr and giac. I have apr now and i run about 15psi. i here the giac puts out about 20psi? I also here the giac is more powerful?

Default APR 15psi is stage 1 software

You mentioned GIAC puts out 20psi - that can't be for comparable stage 1 software, is it? I can't imagine 20psi is anywhere near the working range for KO3s.

If the 20psi is for GIAC stage 3 software, check the pressures on APR stage 3 software to make sure you're comparing apples to apples.

GIAC is generally more agressive/powerful. 20 psi doesn't sound right tho.

Default giac x flash hitting 18 psi on my gauge

i believe when i first bought my car it had the neuspeed chip b/c i was only hitting 13-14 psi...then i got an ams chip and was around 15-16 psi....this giac x flash doesn't spike and hits 18 psi consistently...

Default I've seen 18 - 20 psi on GIAC. Sometimes u get throttle cut with it. GIAC is faster but I did ....

love my APR. I preferred APR for Stage 1 b/c of less agressive boost on the K03's. Unless u want to blow them faster.
