So I ran the Cobb stage 1 for about 3 days, while waiting on my Stratified tune. I was impressed with the Cobb tune...then I got my Stratified tune and it really woke the car up. The stock to Cobb tune was day and night difference. The Stratified to Cobb is a world of difference. I'd highly suggest researching some of the ST tuners and getting one of their "can" tunes to see the difference. They are all relatively affordable and really provide a great bang for the buck!!!!
