2002 Fatboy.  Delphi injection, 124 S&S Hot Set-up with TTS at 6K ASL.   I want to go with HPI but not sure about bore and injector rate.  Thanks in advance,

I have a hot rod 06 98" at 11.0/1 and a woods 9B. I went with the HPI 55/58 with 5.3inj. After suggested by the person who did my heads.Tuned great and couldn't be happier.   Coff 06

IMO look at the HPI 62/64 with 6.3 injectors to be sure you can hold the top end.  Call Jimmy at HPI, tell him what specs you have, where you want power and what he recommends.

58mm is all you'll need.
If you suspect you need more, S&S offers a 66mm cable.

the HPI 58mm throttle body will work just fine. dsv

5.3 injector will easily feed it. While it's called a "Hot" setup the reality is it's not all that hot.
