reburn ? for ken
an aftermarket mass air sensors deems a reburn while you can get by without one for an aftermarket throttle body? what is the stock tb size for a 03 5.4? any benefit other than throttle response with say a bbk? thanks -phil
Yes, an aftermarket sensor does need a reburn if its not calibrated for stock. Make sure you get a calibration sheet with it.
The stock TB is 80mm on a standard 5.4L, 90mm on the Lightnings.
