Hi, is it necessary to retune a car that has already been tuned after doing an FMIC & piping install? I'm guessing yes, but want to verify.

Thanks.

 

I would go with yes. Its pushing colder air. AKA more air because it is a denser charge.

Everything that you add i would suggest retuning. Just the afr and the timing. You dont have the IX so you dont need to worry about MIVEC. But you wouldnt adjust that with small things usually anyhow.

Do you tune it yourself??

 

My apologies ha ha you do need to worry about MIVEC you have a X. But no you don't need to worry about MIVEC with every change. LOL i forgot which threads I was looking ha ha.

 

Did you get the car retuned? What were the results?

 

you will see better gains with a tune but i dont think you will have any problems not getting one.
