14b and 16g horsepower difference in boost?

[tsi1991awd]

My question is a bit hard to explain. I'm going to be installing a 16g turbo soon...I am wondering if there is any difference in horsepower from the 14b.

For example, if you run 10psi on a 14b...is the 16g going to make more power at the same boost level (10psi)? If so, about how much more?

I think i'm the only one here running a 14b at 30psi. Not on purpose though. After the massive exhaust i creep from the old 12psi to 29.6ish. (peak recall on boost gauge)
But the fuel pump runs out of juice at about 22 psi so it jerks and leans out on itself. So now that i've got the external gate, i just need a housing to mount it and manage boost I've thought about going with an evo3 16g, but for one i have a FWD, and for two i doubt I can tune for the power upgrade on an saf-c. Please educate me guys! I'm planning on slapping a 255hp on. I have a guy that runs 11's and he says i won't need an afpr to run the 255lph.

You WILL need an afpr. You can tune with the safc. But you will also need a logger and a wideband to do it correctly.

You don't have to have a afpr. It nice to have one though your gas milage will suffer without one. I have a 255hp rewired on the stock fpr and its fine to me i get about 15mpg average on e85 which isn't to bad. My car traps 115 so it fast enough to get into the 11's without one.

I have a logger and wideband i'm not a dummy. I just need to get more umph from the fuel system. you guys think a 190 will be sufficient and not hurt fuel economy?

Honestly it's not really the pump that hurts fuel mileage I think its more or less the tune.

....meaning your tune will suffer, and any unburnt fuel will bypass the rings where it will end up in the crankcase, ruin the motor oil's film strength, and you'll have metal-on-metal contact. The AFPR is more than just cheap insurance.
