Precats removal questions
Hello everyone and Merry Christmas
I am thinking about removing the pre cats from my CF3 147 2.0 but i am not so sure about the lamdas sensors.
I will get my car remapped and the guy said he can "delete" the lamdas.
The last time i removed the all the cats,the engine broke,thats why i am afraid to remove only precats now!
If i remove the precats and leave the lamdas on,will they affect the fuel mix and will the eml come on?
If i remove them and tell it to the guy who will remapp the car,will he change or adjust anything to the ecu in order not to have problems or eml lights come on?
I am really afraid to remove them although i know that i will gain more power.
Can anyone convince me?
Sorry for my terrible english!
The first Alfa i fall in love was my dad's Spider Duck tail when i was 3 years old.
