loss of power +bad gas millage + smoke

[twofourzeroSX]

Ok i have a few different problems and i think they are all combining into one big pain in the azz. I ran my car at 12 psi on the stock t25 for about 2 months, but took off the mbc for the winter. one day i noticed alot of white/grey smoke comming out of my car. ever since then my car does smoke alittle more than it should. i dont think its the valve seals cause it doesnt do it every time i start the car. Compression tests were fine. Im thinking turbo oil seals...?

on the other note... my gas millage has been HORIBLE... i mean about 12-15 mpg. looking at my fuel rail it looks as tho the first injector is "wet" and darker in aperience. could this mean that the o-rings are shot? could this cause power loss and bad gas millage?? could it be fuel pressure regulator?

to just emphisize on how bad the power loss is...i was dead even with my friends 97 max last night.... i used to pull pretty hard even at 7 psi. PLEASE HELP!!

if you get on it hard in first gear does the car just sputter and put? mine does that and i wana wtf that is. my boost controller shuts off and comes back on. and i also have the smoke coming outa my exhaust im curious to see what the problem is.

possible bloan head gasket. smell the coolant. do a compression test or it could be a bad turbo seal that that dumping oil into the exhast which is has cause the O2 sensor to fail. scan for codes
