My VF40 just went out a couple of weeks ago. I decided to upgrade to the 16g because of the reviews on here and that it was half the cost of the stock turbo. At least from the dealer I am dealing with. I am just waiting on infamous to deliver the oil filter kit and I will be back in business.
I had a couple of basic questions that I can't seem to find the answers to here. One is if the boost is controlled by the ecu will I see any increase in power without a full retune. Second do I need to keep the car running to cool down the turbo after I arrive anywhere. This is what the dealers service guy said to do.
