I want to install cai when i buy it do the tune come with it if not what do i need to do?

 

dont bother with a CAI. remove the silencer that is in the fender well and put in a K&N drop in filter. You will get a greater power increase in this form than a Aluminum tube CAI.

and you wouldnt need a tune anyway

 

as stated no tune needed

 

our cars dont need tunes until you get a lot more into the engine. basic bolt ons will do fine with the old tricks (bump timing and such)...

 

as long as the maf and injectors remain the same the ecu will be fine, unless you have a cam with a lot of overlap or long tube headers, etc...
