Default Kind of a silly question

Ok, sorry to bother everyone with question, but I was curious. I just put on my new ported throttle body on and I was wondering if I should take the predator out there and retune it. Also, I dont think this will work, but my brother threw a code and his ses light is on, will I be able to read his code since the tuner is already programmed to my car? Thanks everyone.

id have to read up on the predator and if you could do that with it.

Just because someone tunes a vehicle does not mean that it changes the way codes can be read. So the answer to your question is YES, Even with a tune, you can still read codes.

Predators can be used to log as well as read the tunes of other cars after they have been locked to a vin. At least, mine could when I had it. I believe it's only the tuning features that are 'locked' - not the diagnostics.

Yea I wasnt sure if it would read codes on another car. I know for a fact that tuning wont work, but I looked all through the manual and it doesnt say anything in there about being able to read codes on other vehicles. I just dont want to try it and something go wrong. Thanks for the responses.
