Throttle Body Bump Stop Mod?

Throttle Body Bump Stop Mod @ InstallUniveristy.com

On an LS1 they found out with AutoTap that the throttle butterfly does not rotate a full 90º at WOT. Does anyone know if this is a problem with the 3.8L? Off the top of my head I can't remember if we have a bumb stop, I'm gonna have to check on that. Will AutoTap give the throttle position on out cars? Any think this would be a worth-while mod?

I think I remember seeing a review of that mod and a few other "free" mods on an LS1 and the result was only a few hp. Probably couldn't hurt, but it won't be a huge difference. I do not know if it is even an issue on the V6 TB's. I do remember that they used the Autotap to determine when they had ground enough material off. You don't want to go too far.
