You can do it yourself. Just remove the throttle body, remove the throttle blade, and cut the deflector off and save some coin.

I did this on my old Bravada and it made absolutely no appreciable difference in WOT performance. I scanned some 0-60 runs before and after the mod and there was no difference. That had a CAI and Hypertech tune on it at the time as well. I averaged 6 runs of each setup running up and down the same road.

Also, when I checked the plugs ~10k miles after the mod, I noticed an uneven coloration from the plugs in the front to those in the back. The plugs in the front seemed to be running rich while the plugs in the back were running more lean. The best reason I can come up with is that the EGR gasses were not being distributed properly with the deflector removed.

The ONLY thing that removing the deflector did for me was increased the pedal off idle sensitivity. It actually was a pain to drive and mileage dropped.

 

Thats kind what i thought, i figured the original blade was shaped that way for a reason.

thats the reason no one here has one on lol,
i would be too afraid i would drop the screw down my intake lol

Thanks but i dont think im gonna do it because of what swartlkk said

 

Tempting mod, I might look into it, but probably purchase a new throttle blade just so if I don't like it, I can always go back.

 

Grab a junkyard throttle body. It is faster and easier to swap TB's than it is to swap the blade.

 

Thanks Kyle, I'll look into it, I'll probably end up doing it next summer, I don't work during school so I need the cash I've managed to accumulate over and above my spending on my Blazer.

Oh, and... But you can have it back now lol.

 

I bought one of the throttle blades from CFM I did notice the quicker throttle response. I raced my Blazer this weekend after putting the new blade in and their wasn't any change in my 1/4 mile times. I'm going to put the stock one back in but I'm going to grind a little off the half moon I took a little less than a 1/4" it seemed to make a little quicker throttle response. I aslo bought a new bigger mass air flow I got it from Granatelli Motor Sports for the cold air intake and they told me to run the stock throttle blade as the one thinner one I bought will make the engine run to lean.

 

What about throwing a few (2,3,4) ports in the blade with a drill? Seems like an easy way to increase flow and still keep a moderate amount of deflection?
