i also threw the cobb stg 2 93 vs the az/ca/nv stg 2 91 pisswater tune, forgot to mention i had the a/p. will do some logging when i get the oil leak figured out. i'm on the fence about throwing the 20gxt on with no wastegate hooked up and limping it for a while (since i think the turbo has to come off anyway to get to the oil return line that i'm 90%positive is the culprit.), or just remove and replace the vf39 and enjoy the added power of sea level before getting used to it and upgrading to fuel the addiction
on a separate note i pull a harder vacuum now at sea level, blow off valve opens easier now, wasn't expecting that.
