06 Z71
 

Hey to all, new to the forum here. Sorry for the long winded post :)
ive got a 06 silverado Z-71 with the flex fuel 5.3 Factory 3.42gears, factory electric fans. mods are KN 63 series charger, flowmasters, Hypertech Max Energy (87 octane). I have just a couple of questions:

1. Throttle body spacer, which one do you guys like the best and is it noisey?
2. Has anyone installed asp racing underdrive pulleys for the crank and the overdrive alternator pulley? do you like them?
3. what kind of gas mileage are you guys getting in city?

thanks to all. have a good one

1. torque curve from trans dapt. i didnt notice any noise, but my truck is crazy loud in the cab, so i may not be able to lol...
3. i get 14 in the city... sometimes as low as 12... sometimes as high as 15... mostly 14ish though

definatelythe transdapt TBS, not sure about pulleys, but I am looking at them, and milage is about 15-17 if I drive normal, 13 if I keep getting on it.

Go with the trasdapt tbs. I am getting about 14 to 16 in city but i drive around a college campus all day at slow speeds.

Hunt - you have got to quit stalking all those college girls, although I don't blame you, but your wife will get pissed when she finds out.
