i put a K&N air filter and BBM big bore throttle but now my explorer's gas mileage sucks...prob bc computer is reading lean and adding more gas than it needs...can this be solved with a performance chip???? if so which ones are good...i'm trying to make a "Typhoonish" explorer(performace-wise)

Welcome to this forum! Does it show a check engine light? If so, then find out what the code numbers are, and don't waste time & money on performance chips.

It could be solved by putting the stock throttle body back on. Just sayin.

Did you clean the oil from the K&N off the MAF sensor?
