Installed my stage 1 tune last week from this latest group buy.
I've gone for 3 drives since and noticed a few things:
1. More mid range power. This is similar in change as the increase in throttle response from standard to power setting. Not a crazy change, but definitely worth the cost alone.
2. It runs way smoother. I was definitely in need of the update.
Tonight I installed test pipes along with the stage 2 tune. Servtronics, cold start delete, etc.
Then I got to enjoy a 45 minute backroad drive home. Lots of 2nd, 3rd, 4th shifts.
It. Was. Awesome.
While the cat removal's influence seemed to produce more rasp then I would ever find acceptable, I wasn't worried as it's currently paired with an otherwise stock exhaust. (Corsa is next).
But the performance and increase in volume was night and day.
All those hours reading posts, threads, and opinions- I find the exact same result: "it wakes the car up" and is worth the Alpine tune and effort to remove primary cats.
Alex, thank you for a great product and providing us group buys.
