I got an EMS and 650 injectors for sale that would work.
More boost is always more fun, but just a little more heavy on the pocket book.

LOL lots of "more" used in that one.

 

If you have the money do it the correct way and find a top notch performance shop. The 'S' is an amazing car and you can spend all kinds of money to enhance performance. I know from experience$$$$$ but I'm very happy with the outcome.

Good Luck.

 

Thanks for the input guys i think ill just leave it alone for now.
