Sound's like boost creep and oil blow-by. What kind of turbo you spooling, and other upgrades to whip? And why in gods green earth havent you upgraded your fuel system yet if your running a bigger turbo than stock. Turn you boost controller as low as it will go, does it still smoke perfussley? Is this really hindering your performance, or does the car go like a great ape but blowing smoke? Could be your valves and internals need some attention. Id do a compression test, boost-leak test, if useing unknown brand or dont know how old boost controller I'd replace along with all lines. Hope this help's, I hate it when my whip runs like shit.
