yeah i went from a pfc to the wolf. major difference. i got out of the tuning real cheap though as my mechanic was having a play with it. we where interested to see the results as no other mods where made except the ecu change. even kept the same pods and first tuned with the afm's just for comparisons sake.
made more power, better fuel economy, better throttle responce, kept all the lovely features like idle up for air con etc. interestingly enough apparently with the wolf it can run auto boxes too.
