Car breaks up under boost only. Runs/idles/drives fine. Roll into boost ok. Wot bogs/hesitation at boost, roll off pedal out of boost runs great. Can drive it anywhere. All stock 1j. New plugs bkr7e set to 25, wrapped oem coils. Any thoughts? Tested for boost leaks, none found. Checked capacitors, good. Ran fine then one day this.

Your coils are cracked. They need to be epoxy and heat shrinked or replaced. Simply only heat shrinking will not work.
