My engine has a blower. I asked my tuner about changing the throttle body. He said " dont bother " and he sells aftermarket speed parts. He is also running one of the fastest promod cars in the country and his street driven turbocharged 2012 Boss makes nearly 700 rwhp. He has been tuning Fords for may years.Just my .02.
