Just a quick question, you say you have a gt3540 - just wondering what specs as mine has the 0.82 rear and is making 480rwhp with slight compressor surge (meaning the turbo has run out of flow) and 24psi, mine also sees full boost early 4000rpms - just after a comparison with when yours sees full boost as im assuming you have a 1.06 exhaust
And congrats on the power and qtr time
