What tool will do this?

Whoops! My car's an M6, does it need recalibrating??

may need a laptop style tune.... never used handhelds.

You can probably spoof the tire size to make it work, or at least close, but you need a real tune (not a handheld) to adjust the ratio

If the M6 needs adjustment -- Tell the predator you have a 25.3" tire. That will get you very close.

If my math is correct -- Its just ratios --- 28.68" tire is to a 3.45 gear as a 25.3" is to 3.91 gear.

It's great to hear all this good news...and happy installers.

Going to see about ordering my set tomorrow.

Question for those running the 3.91s. At 75 in 6th, can you still do a wide open 3rd gear downshift? Or would it be way too high in the rpm range.

That's what I love about the stock gears, is the highway downshift to 3rd. Those with LT's will know what I'm talking about. Ripping 3rd from a 75mph roll to redline is a scream.

No doubt it will go faster as soon as I can get back to the track. 9.99 n/a?

If you're on the fence, don't be. These gears are awesome (and whisper quiet)

Gears are awesome! Always have been in any car.

I remember back in the day when I switch the gears in my '69 Camaro from 3.08 to 4.11.....with only 3 gears....you can only imagine. Talk about waking the dead. Now, highway cruising was obvioulsy the opposite. I didn't care...I was mostly driving around town. Killed plenty of mustangs (back in the mid - late 80's when GT was making a name for itself) from a 10 mph rolling punch.

I now run 3.73 with a Tremec TKO 600 (5-speed) in my '69. Great combo for that car.

Pouncer.....you made out like a bandit. Now you have an excuse to go spend those savings on different mods.

I've found that for the most part I only lost about 200 RPM. I haven't specifically done what you're asking here because I rarely get on the highway but look at whatever RPM you're running when you do this and add 200 to it. That should get you a ball park idea.

Has anybody got a set of these for an automatic?

I feel like 3.91's are a bit too aggressive considering the auto's 1st gear but these are such a great deal compared to the aftermarket 3.70's and 3.73's that it might still be worth it.

Ask your question in the V8 driveline section. http://www.camaro5.com/forums/forumdisplay.php?f=76

I know there are quite a few autos that have the LPE 3.91 gears so it would more likely be seen and get an answer there.

Wow, that's like $691 (U.S.). They are seriously marking up that price!!! I would call Maureen at Rodgers Chevrolet and see if she can ship to Canada. My quoted price from Maureen was less than half that....so you're dealership is a bunch of crooks!!!
