I have first production year Tundra with valve pinging under heavy acceleration. Have done all I can to correct problem; including new ECU plug-in with TRD Supercharger. Changed plugs and thermostat when charger went in as per TRD. TRUCKS MOVES... BUT...SOUNDS LIKE HELL WHEN JUICED. The only thing now is to re-shim valve spacing. Any other help would be appreciated.
