is this ok for my fuel?
Ok, right now i am running the stock 550s for primaries and 1300s for secondaries. I was running stock ports and 396 wheel horsepower to the wheels @ 13 psi. Sometimes it w850s primariould sputter arround 3500 rpms. Is that the tuning or the injectors too small? Also i just had my motor ported and will be wanting to raise my high boost to 18 psi. This should be about 450hp. Will es be okay with my 1300s secondaries? Thanks Jay
oh ya, My turbo is the af61r form davinci motorworks

That sputter is the injector transision. Meaning that is when your 1300's come on.. it'll stumble because it's probably running lean as they come online. You can change the lag and offset settings to fix this if you know how.
396 ATW @ 13psi isn't bad for the 61r I used to run it before I upgraded...
But, that injector setup isn't going to be good for 18psi.
Already at 13psi adn 550/1300 combo is probably trying pretty hard.
I would say that setup will be good for low 400hp. If i were you, I'd go 850/1600cc and you'd be ok for running 18psi on that setup. But thats also going to be dependant on the pump.
Upgrade your injectors if you want to run 450hp safely.

I bought the 850s with the rail milled out. I have a secondary fuel rail for my 1300s. Can I use that one? Is there a way i can tell waht my secondaires are just by looking at them because i cant remember whether they are 13s or 16s. I am almost 100% sure tho they are 1300s Thanks Jay

The 1300s are stock 850s that have been bored out---they're side feed and fit in the stock secondary rail, should be reddish brown in color. 1600s are top feed and fit in an aftermarket rail.
