2004 silverado z71- whats the best tune

[possum07]

I think I know what I did wrong. In your "Redox Class" you mention a "Dataviewer" I havent had that to pop up yet so that i can save the log to the computer then open it up later. I have the USB hook up for the predator and im using Windows Vista. How do I get the dataviewer so i can save the log to the computer, then open it up on Redox to analyze it? Or atleast I think thats where I messed up.?

yeah, you need diablosport's DataViewer app to download the log file from the predator to your pc first...

you can get it from here:

ok i finally got my lifts to where it says no adjustments needed. now whats next.? I want the best settings possible , i also put on a K&N cold air intake and a poweraid throttle body spacer. its still kinda laggin in the low end. i know i ran it 1/8 mi when my truck was stock and it run a 10:80 and after i put all that stuff on it was actually slower, the fastest time i had was a 10:89

loose the spacer, waste of money

[possum07]

but how much of a difference does it actually make if i take it back off?

[05Z71]

It will make hardly any difference at all. TB Spacers are worthless like Canuck said. The only thing you get out of it is a cool whistling sound if you like that kind of thing. Hate to tell you, but if you can't take it back, you wasted $100.

[possum07]

so it doesnt actually hurt it to just stay on there?

[05Z71]

Nah, I don't see any reason why it would hurt anything.

[possum07]

what is the throttle postion VS MPH parameter exactly and what does it change
