probably.... but its not that simple.
a larger second pump would only do so much, needs larger injectors also.
with 1200cc injectors, scaling them and a associated tables isnt too bad. the ecm has a wider range than the fpcm, so i think i ended up scaling all the supplied data by 1/3. everything fired up and works great.
but going to a even larger injector i would have to do 1/5 or 1/6th with 2200cc... you reduce the control at the same time each incremental change does even more, makes idle and part throttle tuning a nightmare. the other option is to cut the entire rest of the tune, fake it into thinking its using a known injector and spraying it into a much smaller engine which sounds like a pita and comes with its own issues.
sooo for now probably not, i will work on going faster with the power i have for while.

After getting the tune a little closer tried to turn back up...I think it just gets to the point where the wastegate pins shut and shoots the boost and injector duty way up, so going to back down a little.
Had a little breaking up, changed the plugs, a few the gap had opened up a little.
To try and keep it cooler while cruising im having welder fill a 16an to 10an adapter that goes to the heater loop so I can drill it out smaller. I'm thinking the heater loop may be large enough and less of a restriction than the engine...don't really need heat so going to try that before any major changes. I tried to lay it out with fittings but going from 16an down to 8an down to 4an and back up to 10an used like 6" of fittings
