I did it the economical whay, Walbro in tank with a Bosch 044 inline, I plumbed a new feed and re-used the stock return. The injector selection for your HP goals need to be 40% larger and a good 1:1 FPR liike Aeromotive or Fuelab is required.
The benefits, well 584whp, not even a slight ping or knock, works great to me.
You can read about to fuel and its cooling benefits, its vaporizes and mix well with the air in the combusion chamber etc, but the proof is in the pudding really.
