Ok, my experience with Power Chips was 100% good. The turn around time was about 2 days from the time I sent them my ecu (which is really easy to pull out) to the time I had it back in my grubby little hands and reinstalled in the car. Joel did everything he said he would. I would totally recommend them. As far as power feel for the reprogram, I could definitely feel the difference. It pulls much harder from 3000 rpm on up. It is in no way a huge power gain, but it is absolutely a gain you can feel. Unfortunately I am now used to the increased power so it just feels "normal" to me now. But I could never go back to unchipped. All in all, I had the extra money so that was never an issue, I am very glad I did it. The car is just that much more fun to drive. If you can spare the cash, I would do it.
