I have a 1999 MUSTANG GT with an automatic tranny. The car has just about all the bolt ons you can get. I took off the catalytic converters off & got MIL eliminators to trico the computer so my check engine light wouldn't come on & put in MAC long tube headers, an h-pipe & welded in Flowmasters. I had a Steeda tune/chip put in back in '99 or 2000 when I installed 3:73 gears...with the new gears my speedometer was off so I got the chip to adjust that & it also adjusted the shift points on my automatic tranny. Good mod & I had the car dynoed @ Steeda many miles & years ago & with all my mods...intake, pullies, exhaust, timing adjuster, cold air etc she pulled 244 to the rear wheels & a best of 14.1 @ Moroso. She consistantly ran 14.3s. Maybe if I was 50 lbs lighter I'd would of cracked into the 13s with a 13.9?
Anyway, one Friday in early 2006 I got laid off from AT&T after nearly 21 yrs there. I was 2 months away from getting medical benefits for life so I was livid. I did what I always did on a Friday night & drove my PONY down to Davie, Florida for the weekly cruise-in @ the Tower Shoppes. After the show/night, I was still seething & I-95 was virtually empty up by Stuart so I said to myself-self let's see what this bitch can do. I had the car up to 132 mph & I had to myself I better ease off the gas before I blow a tire & kill myself or get pulled over by FHP or a Deputy Sheriff & get arrested. I was pleasantly surprised by the speed & power the car had especially in the upper rpm range. My biggest concern switching from 3:73s to 4:10s is not reliving the bad experience I had when I installed 3:73 gears in my 1986 Cutlass Salon...the 2 door body style that looked like the Buick Grand National. That car was beautiful with those chrome rims & raised white letter tires, but a dog of a motor...307 V8 that produced 140 hp. With the 3:73s the ride was over @ 80mph...it was like the car had a governor on it. I just want to be able to hit 110 mph on the highway every once in a while without hitting that virtual brick wall.
B) Is it really worth the difference from a 3:73?
A) Does having 4:10s on an automatic '99 GT work well & can I go 110 mph without the car shaking & whining like a little bitch. Hate feeling the governor feeling I had w/my Olds. Happy w/the 3:73s but if I can get more feel in the seat of my pants & the car still has plenty to go after hitting 110 mph
