Not sure if this is a stupid question or not lol but I'm currently tuned with the DIY short ram intake, will switching back to the stock intake effect my tune enough for me to need to be retuned?

 

Assuming you are using the Evo maf housing which is the same diameter as the stock ralliart intake housing I don't see what the difference will be. As long as your going back to the stock intake with a high flow panel filter.

 

Yes I am currently using the mad housing off the evo x and plan to go back to the stock intake with a k&n filter. Thanks for the help il give it a shot.

 

It may run (somewhat ) richer which, if you have to be 'off,' is preferable for turbo cars...
