**UPDATE**

Have put about 800 miles on my truck with the pulleys, and between both city, rural, highway miles, I'm consistently getting 1-1.5 more Miles per gallon. Didn't really want to comment that early, could have been conditions, but 800 miles of an extra MPG+ I think speaks for itself.

Very pleased.

wow. so $134 for an extra 1-1.5 mpg's. this mod sounds like it WOULD actually pay for itself within our lifetime. lol. can you explain again on the how the power gains felt? and also which part number this is. i've been looking at troyer's pulleys but they are about $100 more than the summits.

Last time I asked my contacts at a couple gas stations no, not yet. I only put gas in my truck from the same Shell Station (unless I'm out of town of course).

I'll double check again tomorrow night at softball.

so are the power gains mostly in the upper rpm range? due to the fact that you can feel it while passing

Correct me guys if I'm wrong, but I'd say it's across the board. You're spinning less for the same speed.

Seeing your thread about underdrives reminded me I picked one up a couple of years ago @ a going out of business performance shop sale. I forgot I had it!

If anyone is interested I'll sell this one for what I paid. 85.00 bucks plus shipping.

That's a STEAL! Wish you had found them before I bought mine!
