Just had it done at Race Proven Motorsports in Claymont, DE by Roshan Patel. Saw some pretty amazing gains afterwards. I went in after installing Kooks 1 3/4 Longtube Headers and ORY, which made my fuel/air ratio 16:1... LEAN!

I went in with 310hp / 322tq with all the mods I have

All of the cars mods are: (Pretty much all bolt ons)
Kooks Longtube Headers 1 3/4
Kooks 3" ORY
Borla 14780, Borla Adjustable Cat-Back
Cat Delete
Stock 3.42 gears
SLP Cold Air Duct
SLP Lid
K&N Filter

After all the dyno tuning, I left with 358rwhp / 372tq

Installed all the mods myself and with the help of friends.

Nice results. Almost 50 hp from some simple bolt ons.

I made 340/350 from pretty much the exact same mods but I was on stock tune and my car wasn't running lean...it's a good thing you went to get it tuned 16.1 AFR wouldn't have lasted very long.

Yeah i know dude i was like im suprised i didnt have any problems with it being that high before i went in.. But those are some good numbers too, my car only has 46K on it so its fairly new so im sure that played a huge factor in the numbers i got
