Does anyone know if it is necessary to upgrade the fuel press. regulator to run 150 shot, i already went to a walbro intank pump. Its a stock motor now, but heads and cam are coming soon.

 

The only reason I can see where upgrading the regulator would be useful is if you wanted to be able to make small incremental adjustments to the nitrous-to-fuel ratio. Otherwise, there really isn't a need to, you can just change the fuel jet to adjust the nitrous-to-fuel ratio.

 

alrite, thanks man
