Tuning would be icing on the cake.
More info can in the above linked thread, feel free to give me a call if you should have any questions!
+1 All 3 of those mod you mentioned Op is what I did. The tune will top it off...and I'm still excited at how well the car runs after all the mods. EAS has all the goodies and they are super helpful if you have questions.
