I guess i will be the minority here and say supplements have made a huge difference for me....but i am a little older than you and you may not need them quite as much as i do. I just wanted to throw in there to make sure you drink lots and lots of water.
I had a custom grind from livernois in my 2v i think they sounded nice and made good power. On 4lbs less boost and through a IC i ended up making 50 more rwhp on a conservative tune.
