dude, 1st thing saga there is no 2 door version, and there is no wide body and spoiler as well.. and if da head looks like saga to u, i suggest u go GOOGLE search now, type "CEFIRO A31" and looks up information and images on it.
At first i told u my car was misfiring rite
Finally today i managed to notice something
Actually my boost was creeping till 0.8 on 4th gear and 0.85 on 5th gear
went home , bought new pcv hoses and fixed em
