THank you .. 3.73s i was looking into gears . the gear calculator is telling me 4.56s to put it close to stock but for the price of gears i might as well sas it.

Gears are not so expensive .. should be about $150 /axle ..
I will check ..

Try driving without using cruise control (assuming you're using it) and you might get some of your efficiency back. Cruise control does not have efficiency in mind when controlling the engine, and tends to drop into 3rd a lot, and rarely locks up the torque converter. With 35s, I'm assuming your speed is way off, which is really throwing the computer for a loop.

I dont use cruise. it does still want to drop into third even babying it and keeping the revs down. my speedo is off 13 mph . was thinking about getting a jet recaliprator.

They are about $260 / axle ..
It's much cheaper than SAS ..

You don't need the Jet garbage. You need gears, badly.

4.56 gears are barely enough IMO. I want to see how chevycrew's tune with the TC unlock programmed out goes.

At what speed? The speedo won't be off by a certain mph. It will be off by a certain percent. For example. Under 25, the difference for me is barely noticeable, if at all. But when my speedo is showing 65, I'm doing more like 78.
I know my speedo is off by ~19%. Which is handy so you can reprogram the ScanGuage to compensate.

I used online tire size calculator and its pretty close to yours it said 20% off at 60 its really 73. I called my distributor yesterday and said they didnt have any companies that made a speedo fixer for an 02. What gear to you recommend donny?

4.56 gears are the lowest you can go in the front diff... you'll need an 8.6" rear end to do them as well.

4.10 if you're sticking with the 8".


Maybe I'm just used to fast cars, but my TB feels like a turd even with 4.56s. I'll be dropping back down to 33s for my next set of tires since this isn't my wheeler anymore.
