First turbo starlet and i have no clue. I got the car standard (turbo, top mount ) and it whistled loads thru the turbo. Since intercooler is on still does it. Is that normal? Sound of turbo spooling? Sounds like a jet lol. Changed knock sensor aswell and it feels different. Boost dont fully kick till like 5.5k and feels likes its holding you back. I havent even coverd the high and low boost tubes there just open. Do they need to be blanked off?
