V10 primary cat

Thanks for the reply did you notice any performance increase or better mileage or more smoke?

Thanks again i was thinking about gutting the primary cats before i get a malone tune but i think i will leave them for the moment, thanks again for your input. what do you think of the tune?

Last questions was there much difference between the 59mm turbos and the stock ones? the stock motor lays over early in the revs, is this why you installed the bigger turbos, dose the tune stop it from nosing over at about 3K.

Thank you.
