Im have a GVR4 running Speed Density with a HKS VPC and all of a sudden i started having a weird problem with my car smoking after i get off the boost. I replaced my O2 sesnsor. did a compression test 150,160,160,150. checked for boost leaks. It only ever does after i boost and then get off the gas(to shift or just to slow down) So i think ive finally figured out what is causing the smoke. I think my map sensor isnt responding quickly enough and its keeping my car super rich for a few seconds. well anyways id like some input if anyone else has ever seen a problem like this. well here are the videos.
