It seems to be about 2-3mpg less in the city, depending on how you drive it. Hwy miles is probably 1mpg less, or none, also depending on how many miles can you go with the verter locked, the longer the clutch is locked in 6th gear cruising, the less mpg she'll loose, so you shouldn't see the difference in the freeway, in the city though, you'll notice it.

Yep. I have quite a bit more of a hit on MPG, but that's more due to the cam LOL.

But those are good estimates.

It has alot to due with the tune as well. My buddies G8 with a ****ty tune gets horrible Gas miles, then another friend of mine with a bigger stall and a solid tune gets pretty close to stockish gas miles.
