Hey all you experts. I hate to start a new thread for this but I didn't know what else to do. Here goes:
I have a 2006 GT. The first MOD i did was the steeda CAI and the X3 tuner with a 93+ tune.
That was about 2 weeks ago.
2 days ago I got flowmasters installed, axle-back no new custom tune.
Today I received my next MOD...4.10 gears and a BBK throttle body. I have the custom tune for this MOD but I have not installed the parts yet.
I wanted to know if I could go ahead and install the throttle body without installing a new tune because my gears will not be installed untill Tuesday or Wednesday.

 

I would just install the throttle body and the tune even though you don't have the gears yet. The only issue you should run into is your speedo may be off a few MPH. Otherwise just wait.

 

yeah I had thought about that. I have a manual so there are no shift points involved. How much would the speedo be off. 3.55 now.

 

My guess would be about 5 miles faster than you really are going. Give or take a couple MPH.

 

Ok, thanks. I think I will just wait.

 

Just return the throttle body and get something else. The stock throttle bodies are fine until you are putting out serious power, so to me, it is a waste to get a bigger one when you don't need one. But hey, it's your car, do what you like.
