Well with the bike I don't know for certain. I'm guessing yours is injected? I put a KromeWorks exhaust and a 45mm flateslide carb on mine and it runs like a champ. The better units for the truck would be the Banks Six gun w/ downloader and the edge Juice Platimum w/attitude monitor. I purchased the Superchips tuner for under $300 so that will suit me for a while instead of paying over $600 and having to install an exhaust to run the max settings. There are also about 10 other manufactures out there but from what I can find these are the most reliable and safe. Keep in mind you can always get more power but you will sacrifice reliability. The torque conveter we have will have some problems supporting the power at the max levels of these units so if you get serious you're looking at $1300 for a heavy duty unit. There are plenty of options out there, my goal is to compete with the Dodge SRT10 in the future and the Superchips just won't cut it but it will give something to play with for a while and pay for itself with the fuel saving. I have the 05 Harley edition also, definately worth the extra cash!
