Can somebody fill me in on this tuning thing. Do you just buy a tune and a cord, and some guy emails you a file which you download to your cars computer? I'm looking specifically at the Trifecta. Cars a 2009 hhr ss automatic. Do you have to install the 3 bar sensors, or will it work with the stock ones? Will my car become problematic and start throwing codes, etc? If I end up changing some of the piping from plastic to aluminum, will it have to be retuned?

I'm new to this whole tuning thing. It's amazing what these computers can do. Trying to plan out my budget so I can get something in the next few months. Also, is the tune able to be discovered by a dealership (I have a warranty).

Thanks guys.

 

I would contact CJ... He is a trifecta dealer. He will mail you a cable, and email the tune. The car drives like a different car and you will not need the 3 bar sensors. Intercooler and piping can be changed without retune. Trifecta has a way, through the tune to make where the dealer can't tell it was tuned, and you can go back to stock as long as you keep the cable

 

if you dont do a canned tune we datalog the car and tweak it.
Shoot me a pm or a email
