What needs to be done to the fuel sytem on the returnless fuel sytem to handle more power I have already got the 255 and 60lb injectors!

 

Well like I said, there's a 40hp difference, so don't be disappointed if your truck doesn't lay down awesome numbers. You should have dyno'd the truck stock, that way you know the gains, HP numbers nice, but the difference is important too. If your truck would have put down say 220hp to the wheels, then it lays down 350hp, with about 5psi, that's fine.

Just run what you got, see how it works out. For now it'll be fine.

 

its funny you mention the flowdisasters. i called flowmaster the other day and the guy just could not stop bashing "the other guy" he said they were using ancient technology. it took all i had to not laugh at the guy. i called to see if they had a 3.5" dual exhaust universal kit with no mufflers. i mentioned i had magnaflow's (cause he asked) and he went on a rant. it was great.
