I did notice power surges around 30-35mph in 3rd last summer. So I'm contemplating about about adding a Dyno Jet PC 3 on my 03 stock VFR. Having said that, I want to inquire about from some of you with experience. How much did you pay for it? I see one here for $260. https://store.58cycle.com/product_p/PC3 VFR 800 vtec 02-05.htm?gclid=CJrAloj3sbQCFal7QgodhDUAPQ I'm not very mechanically inclined, so how complicated is to install? Does it require a dyno run to make sure it doesn't cause more damage than good. Thanks, Merry Christmas!
