You don't bore 4 thousandths, methinks you typo'd.

Fresh bottom ends drastically change tunes. Same car/turbo setup, down to the same head that hadn't been freshened or anything, found peak power at 24 psi vs the old tired bottom end that did it at 30 psi. Took less fuel to do it with (comparatively), but even the timing tables changed.

So... yah, you need to retune.
