My coworker wants to buy an L.... What are the options available for it? What would X plan set him back?

I have modded the hell out of my 02HD and can give him some advice, but what will a well tuned L motor do 1/4 mile and 0-60 with a 4lb lower, changed plugs, intake, and a good chip tune? Anything else you would reccommend he get right out of the gate?

Thanks!

Ken

p.s. buy now or wait for the 03?
