I've had the stage 2 set up on for 5 days now and I love every second of driving it! The Helix system sounds awesome and the car is sooo much faster. I looked around all weekend for someone to test my new power out on and couldn't find anyting worthy at all. Then yesterday at a stop light I ran into something beautiful... a brand-new silver GTO! The guy driving was in his 50's + and was just looking at my car at the light. The light turned green and as I we both started to go I hear him dump it. I was still in 1st ~ 3500 rpm so i put it to the floor and went balls out. I actually had a full car on him by the time we shut down at ~ 60mph. I was suprised to say the least that I was able to pull on a GTO from a "roll". The guy was cool and asked what I had as he notioned to my hood. I told him " about 300" and he nodded and drove off. The funny thing was that two girls in a Jetta saw the whole thing and pulled along side me laughing at him (like they knew how fast a GTO was) and gave me a thumbs up! My first stage2 kill!
