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

 

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

 

Just stay in closed loop or outta boost and you'll be fine..
