Tune without HFC

Corsairprime

My two cents worth: It is a good idea to wait until all your bolt-ons are done. I did the same thing. I wanted to be sure it was time and no more changes were warranted. I then got Berk HFCs and a Osiris Tune in rapid succession. Both also are very worth it. The HFCs make your exhaust and loud pedal wake up when you need/want it to. In general the car is quiet on the highway at 60-75 mph. I bought the full AAM S-Line exhaust and cold air intake. It was muted until the HFCs were installed. Then it turned into a racing machine sound. It's loud if you want it to be and more responsive. Also regarding the Tune: the car picked up 35 ish HP, not bad considering it's all bolt-on.

I know: take it with a grain of salt, HFCs are not for everyone, but I like my setup better with it.
