I'm pretty new to all this and tried to search but couldnt come up with what i wanted. Im about to install a set set of Pacesetter LT's and want to know if i shoud get my car tuned after. Im looking into MADZ28 and i see he has the $225 tune with $50 retune. Should i get that or should i just do the $150 deal to have my rear o2 sensors deleated? Also would me getting a ORY or a catted Y make a difference in the tune? Thanks for any help.
I'm in Binghamton NY. Now whats all your feelings on o2 sims? Sorry if I'm asking all this crap over again but im just real undecided and want to get this crap on there before the weahter starts getting nice again. Thanks again.
