Pretty excited about it when I got my car back today. Drove it around and it seems to pull harder, or at least the rpm's climb faster. Couple of problems I noticed...the steering/power assist doesnt seem to be as smooth as before. kinda like the power assist is fighting with me. Feels like its not turning all the way and I have to muscle it to make it engage. The installer did say he dropped the steering arm, but nothing else was tampered with. Taking it to the dealership and try to fix it under warranty. The other thing I noticed is the car seems to vibrate more, especially when I turn on the ac. I chalk it up as a small nuisance, but its irritating. I checked all the bolts and dont see anything out of whack. Is it normal for the car to vibrate a bit, I thought the headers might be rubbing against something, but nope. All in all, Im quite happy, just gotta get the steering checked. Hopefully pickd up 10rwhp or so. Cams next baby!!!
