What are the pros and cons to adding a vance and hines "Fuelpak" to my '09 HD Fatboy?

Just weighing pros and cons to adding a Fuelpak to my bike. I currently have stock exhaust, but have considered drilling out my baffles and was wondering if buying this would be necessary if I drilled them out. I've heard that HD's already run a little on the "lean" side. Also, if I left my stock exhaust as it is, would a fuelpak still be a good idea or just not necessary? Thanks|||DON"T DO IT!!!! .....SERIOUSLY!!!!!


What you want is the DynoJet Power Commander 5. The V%26amp;VH FuelPak is seriously out-dated technology. In '07, HD started using Oxygen Sensors in the fuel injection system, with the addition of these sensors, HD's can now run in Open %26amp; Closed Loop modes. HD's fuel injection is HANDS DOWN state-of-the-art over any other manufacturers with injection. The PC5 is currently the only "piggy-back" system on the market that is fully compatible with HD's new fuel injection system running Oxygen Sensors. HD's O2 Sensors are narrow band, they only read air/fuel ratiosfrom about 14:1-to-15.2:1. With the addtion of the PC5's wide band sensors, they will be able to reada/f ratios from 11:1-to-18:1, allowing WAY BETTER tuning capabilites.


The V%26amp;H FuelPak is nothing more than a simple box that you adjust by enterering #'s from maps that you find on the V%26amp;H website. Dyno tuning is possible, but extremely difficult and expensive, also it does not allow for any tuning of the O2 sensors for economy AND performance in the mid-range cruising speeds. The FuelPAk is just a "CHEAP GET-BY".


The PC5 is FULLY DYNO TUNEABLE FOR MAXIMUM POWER%26lt; PEFORMANCE AND ECONOMY.


I could go on and on about this, explaining it in great detail, but I'll keep it short with just the basics. I have been working on Harleys for about 20 years and do alot of Dyno Tuning on HD's....I LOVE their injection sytem, with the RIGHT FI Controller and properly tuned by a GOOD DYNO TUNER.....you won't recognize your own bike when you get it back!!!!


Here are links to the PC5 and the FuelPak.....read up and compare for yourself.
