Gearvendors... anybody?

[richc22a]

I put a lot of highway miles on my 07 6.0 FX4 CC. Cruising down the road 75-85 pushing a wall of air packing a little weight, and sucking diesel... thoughts are wandering towards a gearvendor unit. Now I know that it will probably take about 100,00 miles to make up the cost... but the idea of cruising 75 at maybe 1400-1500 rpm is enticing. Does anybody have REAL WORLD experience with a gearvendor unit in a diesel 4X4??????

Bump, I wanna know too. I think that would be sweet too!

I've driven a couple of trucks with these units and actually wanted to get one for a truck I had. I have seen them on everything from muscle cars to dump trucks. Problem is there very very very expensive. The one I priced out for an 87 chevy 4x4 was $3600. Needles to say I didnt get it. But one truck I drove with it in particular was an F450 6 speed. It took the rpms at 70 down to about 1900 rpms from about 2300. The majic fuel miliage rpm on a powerstroke is 2000 so right there it helped a good bit. I dont know what it was running for fuel miliage but I be it helped.

I had one on my '03, should have removed it but didn't. it gave me close to 3 mpg ( 17 to almost 20) and dropped my RPM down to a beautiful 2100 @ 85 mph. I loved it and would buy it back in a second, if I didn't have many more mods planned first.

Ahhh.... the stuff of dreams... I suppose the idea would be to have a 'TUNE' written that would crank out low rpm torque that would conserve fuel... gearvendors is at [url=http://www.gearvendors.com]. I know that the 6.0 is factory set to be capable of pulling the maximum payload at any point, meaning it has a program that encompasses all the trucks potential uses. Getting it set (tune) to perform at a specific rpm for economy should not be difficult. Any 'tune' savvy inputs, or is it more the bore/stroke set up that determines low end torque. A side note, the in line 6 has been said to be the best configuration for torque... thoughts????
