Ordering new fuel pump. Stage 2 Map... more power, more torque, bigger smile
That will be the limit of the TMIC... guess that's next on the list.
EDIT: more info - It may not look like much but these replace the standard fuel pump internals (camshaft driven fuel pump) and lets me safely raise the boost above 18PSI. The current Stage1 map runs 16.5 PSI and the next map (Stage2) runs 17.5PSI.
Plus adding a bigger TMIC means I can run 19PSI Stage2 map.
