Should not be too tough to find gears for a 'domestic' center section. :D

I don't think LS1_Edit is available for the GTO just yet, so you will not be able to calibrate the speedo until that happens. If you have an A4 car, you definitely need to wait for an 'Edit' because you trans shift points will be WAY off.

LS1Edit is already available for the GTO's straight from the mouth of the Carputing guys. Just FYI.

OK, I am glad to hear that, but I have not seen anything about it on the mailing list (though I don't read every post and I don't actually own a copy...yet). Thanks for the update.

We're gonna regear our car after it gets back from Magnacharger. Probably going with a 3.90 set. I just wanna see how the car reacts with the factory gears and supercharger before switching.
