Is there any way to adjust/fix this? Is it actually causing any tangible problems with regards to performance?

Are you testing this while the TB is on the manifold and someone is pressing on the gas, or just opening the blades while it's in your hand?

You can adjust it in the PCM. I had the same problem and had the high TPS voltage code tuned out.

Opening it by hand while it's already on the engine.

I think everything's cool with the tune, just wondering if the blades being slightly tilted like that will affect performance at all? I figure even if it did it would be like 1-2 hp at most. Solid roller 355 for what it's worth. I've heard people talking about this problem with the Holley and wondered if it mattered in the grand scheme of things.

Let someone press the pedal and look at it then

Yes it will most likely cause a problem. It will throw a TPS error first time you go to WOT and send the trans into limp mode. Mine shifted from 1st to 3rd first time I ran the Holley TB at the strip. Assuming it's on an OBD1 car, the quick fix is to turn off Error 21 (TPS sensor high) in the ECM Switch table. The correct fix is to bend the stop to prevent the blades from going past 90 degrees.
