Doubtful this will work in solving your boost creep issues.

i agree that is probably not the issue. you might want to have your customer do a boost leak test.

The boost creep issues is with the waste gate or exhaust housing.

wastegate size or plumb out for sure.

turbocharger size for boost ran with wastegate size proportion as well.

There a number of ways to solve this problem, however your colleagues suggestion of a larger intake is not it.

to boost consistency across the band will sure help a lot.. look at the boost increase is linear so you would expect a more linear power curve. its like you are running 6 psi from the start so you couldnt expect a lot of power from that.. then peak boost hits towards the end of the power band. sounds like a boost control issue to me more than anything
