So the good news is i just bought hp tuners pro and I'm ready to learn some basic tuning. The not so good news is that i am going to be practicing on my 2011 ZR1. So far i have done kooks 1 7/8 headers and the the catted x pipe so i think a good place to start is getting my check engine light for that fixed. After that i am going to be installing a 14%od lower and 2.6 upper pulley along with a BTR stage 3 cam Meth and Injectors. i am looking for advice on what book or books to buy to get started on a basic tune for the exhaust work.
