Next Mod: Gears or Custom Tune

Gears

Gears. I have 3.73's. If I had a second chance I'd have gone with 3.55's. 3.73's gets through first too fast

Gears. I agree with the first gear essentially not being there with the 373’s. I said in another post I’d go with 355, if I were to do it again.

Also, with 3.73 I think I’m running out of 4th at about 110mph. Running out of 4th at 120 would be better. With enough hp, 3.73 would be too steep for a 1/4 mile run

There isn’t enough done to your car to capitalize on a tune. You’re better off just advancing the timing just a bit yourself, as long as you don’t go too wild.

4.10 gears all day. I drive freeway at 75mph with a 26in tire and a .68 od and I sit right about 2700rpm. Interestingly enough I seem to get better fuel economy than when I had my 2.73s. Go figure. Did 100 miles to Charleston and got 22mpg.

Honestly, the 3.35 first isn’t as bad as people say if you can mash some quick 1-2 shifts . Just gotta keep the wheels from getting away from ya.

The tuner is pulling your chain. Don't let him screw up the stock tune. It will NOT gain 10-15 more hp than simply optimizing your base timing and leaving the stock tune alone, even if he manipulates a dyno to please you. Plus, if you're in this for the long haul, you'll need a tune again after you make any significant modifications. If you have or buy a timing light, we'd happily talk you through the process of advancing timing and get you a "free" 5-6 rwhp. In the future, you could adjust the timing on your own within 5 minutes to switch back and forth between 87 octane and 93 as you see fit. Where are you from? Maybe one of us lives close enough to lend a hand.

Don't fear the gear. I gather you have a '95 Cobra with stock size tires (255/45/17)? If that's true, then with 3.73s, you'd go nearly 125 mph through the traps at the limiter. Granted, you won't make it to that speed in the 1/4, but the point is that you won't run out of gear. In fact, 4.10s would be pretty near perfect through the 1/4 for your power band. I never felt that 1st was useless on the street with 4.10s in my last '91 Mustang that went 12.63@107mph on all-season 225/55/16 tires. I cut a 1.83 60' on those tires and I needed the gear to do it. But, to each their own. 4.10s definitely bring the RPMs and drone up on the highway. Good luck, man! And whatever you choose, I hope you have a blast with the car.

I do like my 373s. I’ll probably never change em out. I just drive it on the streets anyways. Works for me.
