That link didn't work, Lars. I suspect this is the one you meant: http://dygytalworld.ehost-services13...ghlight=summit

Thanx Jack!

The other thing that bothers me in that my constantly growing knowledge of mods and tuning, is that some to most of the advertising out there for these types of products is at WOT!(wide open throttle)

I am not bashing anyone particular vender!
I just thought to suggest this because how many of us have been mislead by not particularly false advertising but the lack information given to us when we are deciding that we need more POWER!

Like the udp.
13 hp at wot hmmmm=maybe 2-4 hp in daily driver real world mode.
The ideal hp can be acheived racing down the track but let's get real. How many of us get to do this?

Ok off the soap box.

So when you looking at mods multiply the hp by .25 and that maybe the more realistic number you are going to get for your daily driver.

Excellent point Lars! I'm glad you brought it up.

What we need, as you say, is some information that is more relative to our daily driving habits. I think fuel economy is one such metric and passing performance is another. I can see towing capacity, for those that tow. What else is there? Longevity?

The longevity part of the equation should be taken care of by an approval sticker found either on the crank pulley or a lose one to be applied by user in the engine bay.
The sticker indicates that the pulley has passed testing and is rated to be used on the motor it is to be installed on.
Can't really crawl under the truck right now to see what it says. But if I remember right it should be SFI Approved?

I was thinking more along the lines of what the mod could do for the longevity of other components in the truck (possibly by reducing wear and tear). For instance, I have seen claims that u-drive pulleys might extend the life of water pump bearings since the pump is spinning somewhat more slowly. I suspect this benefit is pretty small, but maybe it's worth noting (and I don't really know how you back up such a claim).

But, I like the label that the device has met certain minimum requirements and so should be safe to use. Kind of like the UL sticker on electrical equipment.

When I put the UDP from Troyer on my truck I did notice that I got slighty better mpg, and better passing power. Been on my truck 2 yrs now with no issues. But at the time it was installed I also had the AF1 CAI kit installed at the same time so I can't say which gave the better gain but I'm happy with it.

97xl,
tell me about your wheels - what are they, what size, etc. i like the look of them.
