i have been trying to get my gs400 running right since i bought it. it has rmm supercharger kit and i have put on a areomotive fpr and made the fuel rails feed thru with return to the tank. i have it set at about 40lbs pressure. i also have put in a large external fuel pump and filter and wired it in to the stock fuel pump wiring but its doesn't keep it at full voltage all the time its regulated because of the stock head end fuel system. i am going to run a relay with a switch instead. that should help with pressure. but my issue is that it as been backfiring. what could be causing this may be timing off a little when the belt was changed i am just wandering what's causing the issue so i can fix. any help would be appreciated.
