AU. powerchip gold 92-95
 

Austrailan powerchip fits into ECU, small power increase, better throttle responce. New was almost $500 paid over $250 used. Sold car. Make offer

Are you sure this is for an SVX?
the Powerchip site comes back with this message for all (OBDI or OBDII)

"Unfortunately there is no Powerchip upgrade released for the Subaru SVX 3.3 at this time. Your vehicle has been seen by Powerchip but with our current technology we cannot upgrade the ecu at this time."

Powerchip actually DID a chip for the SVX long before anyone else. If I still remember correctly, one of its positive points was that it deletes the speed limiter...

Hit the search button, maybe you will get lucky ;)

All I know is what is printed on the chip, and the open covered in plastic slot on the motherboard. Only 10 HP, decreases the delayed throttle effect. Latter 96 on up had upgrade from factory.
