im debating on either to get this mod or not from american muscle....its the combo pack of the 3.73 gears with the sf3 tuner. i have a 04 gt with a few mods cold air intake,70 mm bbk throttle body,stack intake spacer, off road pro chamber,borla cat back,and steeda short throw shifter.....i was just wondering if this is going to do any real big difference on my gt since i want to get the most bang for the buck....its a daily driver but i still like to get on it w.e i can

 

What gears do you have now? Either way from what I hear, 3.73's are the best all around gear for the person who wants the power but still needs the daily drivability? I can't speak to much on the tuner but I've heard a lot of negative feedback. I know it turned my old 04 f350 power stroke into a race car! No joke! but as said, I've heard that they just don't do the same magic in a gas powered vehicle.

 

I'm going to assume you have stock gears. It won't be a big difference..it will be a HUGE difference lol. I had the SCT tune/tuner from AM and 3.73 gears in my '03 and it made it feel like a whole new car power wise. You won't regret it.

Meh Necro post!

 

I went from 3.31's to 4.10's two weeks ago, and all I have to say is OH MY GOD!
