I really cannot tell you about the difference after each mod was installed. With the exception of the tune, all the mods were installed at the same time. This made for an "interesting" transformation. I will do the tune probably around September or October. I didn't do a dyno, but I'll do one after the tune. I can say it pulls SIGNIFICANTLY harder. Also, you will see the boost gauge moves faster and farther to the right.
