Soooo I'd change it up a little, once you hit 450hp-put on your mod list injectors if you plan to go after more horses. especially 500+.

I run the 255 lph Walbro intank.... No issues so far and I have run this for nearly a year at 11.8 afr at 5800 rpm seeing 185 kPA logged through hp tuners... Can't answer yet for 600+ rwhp... yet....
