also , would 02 sims be cheaper and do they really work . where do you buy them cheap . thanks

 

A mail order tune can run you around 150 bucks or more. It is possible that a tuner could just program out the rear 02s for a smaller cost. The 02 sims will run around 90 bucks for a plug-n-play pair from Summit, Jegs, or Thunder Racing. There are some cheaper 02 simulator variants out there that require cutting and splicing into the actual harness.

 

Well, it helps if you post WHERE YOU ARE when you ask something like this....
