Hypertec...like all generic chips are...JUNK. Their only fuction is to bump the timing, you can do that yourself, so find the receipt and send the chip back where it came from. There is no 'magic' chip that adds power and it's a shame they can adverstise it like they do and charge what they do. You'll make more power without the 'chip' and setting your timing at 13-14 degrees.
