need some advice

[kramer03gt]

hey all.. i have a 03 gt, auto, and i just put on the demolet cai, with the dragon 75 mm tb and plenum, and i have my slp loud mouth on the way, but i am thinking about my last mod for the year is going to be gears and a diablo sport tuner, but i was wondering what the real difference would be between 3:73's and 4:10's i drive 20 minutes to work everyday, and im not to concerned about the gas milage thing, and from time to time i will drive to my parents house which is a good 250 miles away from were i am, so im trying to decide which ones would be the best and all of my driving is mostly on the highway some city if that helps at all, my main goal is to get the car to be able to keep up with cobra's and firebirds and camaro's the normal competition, so your input would be helpful!!

thanks alot!!

Id go with the 4.10's and a xcalibrator over the diablo stuff. Id also get a tranny cooler.

If your not worried about gas mileage and your goal is to keep up with cobra's and LT1/LS1's then definetely go with 4.10's. Its gonna take a little more than what u got to keep up with LS1's though even after the 4.10's.

I'd have to agree with the 4.10's. The tune you can honestly skip at the moment if you can tolerate your speedo being off a bit. Look into spending that money for a shift kit for your auto.
