Evidence would be my car about 2 years ago,
Stock turbo and cooler with safc 155rwkw.
Stock turbo, fmic, safc 183rwkw.
The fact is that the stock cooler is a piece of shit and should be tossed in the bin.
If you get a fmic installed on ur car, then you would atleast get a bleeder which costs $90 to raise the boost from stock as it is so easy to install and use so you get the performance increase.
Y are we arguing?
I was enjoying GTTR34 getting a baging from everyone instead
