Thread: overkill tune

Tune is 150 plush shipping. I have read so much on this forum about needing a tune and how much it changes the car. One thing was for the transmission changes that actual make the car drive better be also help it from damage. The second i read is the tune gives better performance due to the modified fuel and air.
I guess the fuel and air only need to be modified if your having knock, so if little to no knock then maybe it isnt needed.

I had stock manifolds before so with the addition on SD headers that should only make knock less.

But if you are going to do it, delete egr codes and cat codes, unless you are keeping the cat.
