Fuel Needed For 12psi?

What fuel mods would you suggest for a GS-R with JRSC running 12psi. Currently I am on stock injectors with a rising rate fuel pressure regulator and Walbro 255 pump. I'm experiencing detonation but only sometimes. What do you suggest?

What he said. 2 bar MAP sensor is crucial to read above 10.6 psig, JRSC need ignition maps redone to avoid pingies.

What fuel management system do you suggest? Keep in mind that I may eventually end up selling the JRSC to go turbo.

Hondata
Uberdata
AEM EMS

Any one of those 3 are good, uberdata requires that you have a WB O2 and a laptop to tune it yourself though.

Re: (larryd)

call around and check around to local shops and see what there best at tuning. if someone tunes uberdata go with that. other wise hondata tuners are pretty common.
