hello ive just had a customcode phae 2 remap on my k03s conversion a3 and i think im having boost problems. the car only makes a spike of about 16 psi at the most, then almost instantly falls to about 14 psi up to about 4500 rpm at the most then it keeps dropping and at 6-7000 its about 8-9 psi, is thiss normal or to low. I keep reading posts bout k03s cars holding 15 -16 psi all the way to the redline.
