I have a Muzzy slip on and a K&N filter on an 03 ZX636 with 18k on her. Im also about 100ft above sea level. I have a power commander 3 on its way and from what I understand the pre made maps online are not the best. Im looking for someone who has a custom map that would work for me. A map with a straight pipe instead of a muzzy slip on would be just as great. If I get a good map with maybe a dyno print out, I could see $20 in your pocket ( or paypal account) for your troubles. I don't have the money for a $300 dyno tune. Thanks!
