I asked a question about this on the performance forums but of course they're not the least bit interested in fuel economy. Hopefully I'll have better luck here but since I've got a 6.0L V8 I'm not sure anyone will take me seriously. Anyways...

I was wondering if a camshaft (properly tuned) can add enough fuel economy to make it worth while vs just an economy oriented tune.

Background info: Jeep wrangler, LQ9 conversion, 4.11's with 30" tires. Currently gets 16-18mpg city/hwy, I'm not expecting something like 30mpg but 22-24 hwy would make it worthwhile to do both. Otherwise I wouldn't make up for it over the 100k I'm hoping to get out of this setup.

I know I could do gears but mind you this is very expensive when you're talking about doing two sets for a 4x4.
