I'm sure Mike (HAMMERDOWN) does feel more power.
I have been having Mike handle my tuning needs for about 4 years now. He's easy to talk to and work with. Knows his stuff.
I highly recommend anyone to use his services. If you live with in driving distance, you need to meet up with him and have him plug his lap top into your car and go for a drive.
