biggest turbo for 2015 pump

Putting my 2015 pump in and wondered if it would provide more fuel than the turbo can use. I have a 63mm non vgt currently.

i doubt it.

Would I benefit at all moving up to a 64 or 66? I'm just looking to maximize the amount of power from the truck without breaking in to dual pumps.

have someone write you a tune that maxes out the pump. See how much smoke you have a WOT. If it is a light haze, going bigger on turbo wont get you anything but more lag. Seeing as a 64mm vgt will use more fuel than a 15 pump can put out, i would bet a 63mm non-vgt will not leave any fuel left over.

Thank you sir, you answered my question. Kind of thought that the 15 pump with 63mm might be just the sweet spot combo. Currently I have light haze at full throttle with the 11-14 pump on GH tune, TD will drain the rails if the truck is under a load with full throttle.

63mm non vgt and dual fuelers on a 2012 truck, one of our employees.... makes 610hp and drives beautifully. One of the most fun trucks to tow with I have driven.
PPEI tuning, MPD turbo kit, BD Fueler....

15 pump should be similar just a little less power capability.
