HP Gained

You'll lose 5RWHP on the dyno with the 4.10's. You'll gain only afew RWHP with the catback and CAI. If you just have the basic performance tune in your Mach, I'm not sure what you'll gain. It's better if you get it dialed in on the dyno with the mods you've made. But you should gain about 10RWHP and RWTQ when you get it dialed in.
