Just looking for input, havent see anyone say they found the problem. Anyone with a bigger collector piping and bigger turbo ar housing fix this problem? I have upgraded downpipe and ehaust dump. I drop 3psi from 11 to 8 by 7k rpms.
Looking for any info you may have on the EDP kit boost drop off. I have the same kit with the 7475. Have both upgraded downpipe and dump. Did upgrading the turbo to the 7675 solve this issue? Any info would really help, my car is dropping 3lbs at high rpms.
