Thanks, I'll let you know how it turns out.

 

i have the torque curve and im satisfied with it, so i guess both work well

 

I have the airaid poweraid and It gave me very noticble milage gains. Im very happy I tried to test it out.

 

Yes I have gotten milage gains as well, not sure exactly how much, but at least 1.

 

I got the Torque Curve from Summit racing for $50... About 1 mpg and a slight whistle, but only under acceleration...

 

Ok, another update. On the way to work this morning it was@ 81 degrees, and running in traffic at 70 mph I gained a ittle more that 2 mpg, and coming home@ 95 degrees at same speed I gained a little less than 2.

 

what is the difference between the torque curve and the smooth bore
are they any different in price

 

The general consensus is:

Torque curve = low-mid gains
Smooth Bore= mid-high gains

Same price. I got mine from summit racing, as did a few others on here ...about $52 w/ shipping.

MFG: Trans Dapt

 

me too. got the torque curve and am pretty please w/ MPG Gain

 

If you go on Summit Racing and look up the Trans Dapt throttle body spacers for our trucks. They have a description of both the smooth bore and the torque curve. The smooth bore is designed to produce a mild gain and the torque curve is supposed to be a much better gain. It's basically like stage 1 and stage 2.... The rpm range that the power comes in doesn't have anything to do with them.
