My car is tune with a kn dropin filter and catback exhaust. its been a couple of years since my tune. i want to install my megan dp and cobb intake before i go tune my car next week. If i install those parts will it affect my afr n drivability until i get a tune.

The dp wont really matter much but the intake will change your afr's quite a bit, you can install them just watch your wideband if you have one and if not just drive normal and you'll be fine

nothing gonna happen with afr you wont feel a thing.

the he.ll if they dont change. you personally wont feel it in the car but the cars afrs will change a great deal since it changes what the maf is reading especially from a drop in filter to a cone filter now. go ahead ask your tuner and see what he says

egis

ok i meant it wont be dangerously lean or rich.OP probably needs to know if its ok to drive untill he gets tune.
