I'm not sure if you would pick up any spool from a good EFILive tune, the PPE is well proven and respected. I'm thinking you will need a re-gear to 4.56 in order to rectify what you've done with the big tires.

Run that thing in Tow/Haul in the meantime to keep the revs up a bit. Revs = airflow = spool.

Your lift... plus big wheels/plus big tires = more lag than stock. You are trying turn a lot more mass. Have you checked/replaced your fuel filter lately?

Wouldn't bigger intercooler pipes actually increase lag? (More volume to compress?)

That has not been my experience. Bigger tubes = less resistance. The faster you can get cold, dense air into the engine, the faster you can make revolutions. The faster you make revolutions, the faster you generate exhaust. The faster you make exhaust, the quicker your turbo will spin. Repeat.

Agreed, and a regear would definitely help get those big tires going
