LOL no probs m8 :D

 

Willie, all I can assume about the boost raising, is that the air filter is less restrictive, so the pressure is different in the turbo inlet tract. The stock solenoids take a feed from the intake tract as a bleed off to increase the boost under non safety boost conditions. Although thinking about it the pressure in the tract is actually higher (less vacuum) so you'd think the wastegate would open earlier....

 

CheerZ,
