I agree 100%. I track my car hard, their k04 file is great.

Interesting how some files work great for some and yet on the same car don't work for others

Am I the only one who thinks 29psi is a Lil out of efficient operating range for a K04?

Nope, you're not. The aftermarket is competitive and customers don't care about anything but peak numbers so they can brag and play rice rockets on the street.

Have you seen the compressor map for a k04? I am actually curious now myself.
My understanding is apr uses stronger wastegate to hit those high numbers

IIRC, Marcel with HPA keeps their K04 files under 25psi peak with 21-22 hold. He kept talking about anything higher is just out of the turbos efficiency range.

Yea it seems like there is so much variation. So either the efficiency range is wider than originally thought, or tunes are just pumping hot air
