HW Carb kit w/ TPI Valves. - and it's less expensive

I''m sure someone else will chime in with a technical reason as to why here shortly.

I know it is my kit and my opinion is biased but our kit beats it to death and most people can't get that thing running right and it's too loud.

Reason it does not run right is the loss of vacuum.

I hated my aFE intake and filter so bad I sent it to Todd at Hunterworks for testing. He knows what he is talking about.

It was so loud that my wife rode about 1000 feet and told me to stop so she could get out and run away. The HW kit you would not even know it was on there, as there is no change in sound, only performance.

Don't have any #'s but my guess is:
HW = lots+++
AFE = 0 HP gain unless at wide open throttle with high rpm's or else you have a set of FCR carbs on there, then the AFE will work good for you. FCR's are only a $1000 upgrade!
