IS IT POSIBLE TO PUT THE K&N FILTER SYSTEM AND A LESS RESTRICTIVE EXHAUST ON A 502 MPI WITHOUT CHANGES TO THE CPU SYSTEM WITHOUT HURTING THE ENGINE.

if it isnt running leaner you havent made any more power, if its running to lean you can install an adjustable fuel regulator and bump up the fuel pressure till you get a good reading on your plugs
