Writeup: Throttle Blade Removal Mod

Notice any gains? Realistic or imagined?

to be completely honest, nothing really. , it pulls slightly better heading up the hill to my house, thats it, seems the same as before :dunno:

I've noticed a little more pep, but the only REAL gain I've noticed is like you said- on hills. I usually run cruise control and my truck used to always downshift on several hills- no more. So I KNOW it helped a little bit in my case.

I removed the lip yesterday along with the resonator box. I've driven the truck a couple of times, but I keep forgetting that I had done the "mods", so I haven't nailed it yet to see. I truthfully don't expect any difference, but at the cost, I had to do it.

I'm sure that lip was put there by GM for some reason, just like the resonator box was put there to tune out a noise at a certain frequency. Since the box only created stagnant volume of air, I expect no performance change from that. It may end up being a little noisier at a certain rpm and that's okay with me. It's not like I can't put it back in 5 minutes. The throttle blade lip is gone for good, but there doesn't seem to be any evidence anywhere that it was negative, so why not take a chance. It does seem that it would open up the breathing some, but I don't know if that is the choke point in the intake.

Cost of both mods, $3 for the plumbing cap. Real advantage is that some things will be easier to get to in the future.

Could have saved $3. Any cap from a spray paint can will fit snugly over the lip on the intake elbow. I just used a hose clamp for cheap security. Done it this way on all 3 of my Vortec trucks. I trimmed the cap so it was shorter, and not as bulky looking.

subscribed. Id like to do this when I pull the intake to do the spider injectors and new gaskets. Might as well make a day out of it while I am in there.

How do you like that flip-flop ratchet? I've been thinking about getting one (I think the same exact one).

I can really tell what it does when the roads are wet. You really have to have a light touch on the throttle or the tires spin. I think that must have been the whole purpose by GM. By reducing the airflow at a barely open throttle, they reduce that initial torque to let the truck get rolling before the power comes in. It is really noticeable in bad traction situations. I think it would be a handful in snow like this.

Moral of the story, I need wider tires.

I did mine a few months ago and notice the gain's at take offs and when I step into her when passing.
I took another one off a truck at the bone yard and had my partner Oakdog from TYF trim it down and just swapped
it out in a matter of minutes.

Nope, no ill effects at all
