I know its a good tuning device some people run them full time in there cars.My question is just a basic one going to do all i need it to do? I think you can get a innovative kit for around 200.00 are these the best for the price? I also want to use it on our race car to tune with we run race gas 110 octane.I know its heard on the 02 but how hard? how long will it last anyone know? is there anything i can do to prolong it or clean the 02? Should i place it a little further back in the system?
