I have a completely stock 2007GT. I am considering the following modifications to the car. Cat Back Exhaust, Cold Air Intake, Enlarged Throttle Body, and OBD Tuner. Can I define one of the tunes for performance, one for everyday driving, and one for fuel economy?

 

Save some money and don't bother with the throttle body mod. They are usually more trouble than they are worth and are not necessary for lightly modified cars.

 

as far as the tune question goes; yes you can have 3 different tunes in an sct tuner from BAMA/American muscle. I'm not entirely sure about other companies but I'm sure they offer multiple tunes. I know a lot of us on here have bama tunes on our cars but I can never really convince myself to use the street tunes...

 

Jd is right..the throttle body is best when you go forced induction..I use breenspeed and they offer all three as well..I think if I could use my "street" tune for a coffee table I would because thats about how much use its gotten..

 

What is the purpose for your vehicle? Daily-driver, street-only, street/track, track-only? If track, what kind of track? (drag? autocross? etc.)

 

Throttle body is waste of money. I used the Brenspeed tune on my 05 and loved how changed the car. Better throttle response, more power and torque.

 

Thanks for all the helpful information. I think that this ol'man will avoid the performance enhancement and inevitable tickets/insurance premiums and just buy a louder exhaust to further irritate my wife and neighbors.

 

Living in Western WA, I try to avoid discussions about fuel economy- i'd always lose that fight.

I blame the prius going slow in front of me. ARGHH

 

From another old fart......get the CAI/SCT......it makes a very nice difference in the way it will drive.

 

Get brenspeed tunes. They have the best customer service on this forum. They can hook u up with whatever your needs r
