How do you do the throttle stop mod to achieve WOT and is it worth it? Also I seen that casper elec. is selling some thing that plugs into you TB that speeds up throttle response it is called somethin like a "TPS, TPC or throttle enhancer" it cost like $80.00. Is it worth the $$?? <img border="0" alt="[guns]" title="" src="graemlins/gr_guns.gif" /> <img border="0" alt="[Pontiac]" title="" src="graemlins/formula.gif" />

 

No.. is the throttle is opening all the way, I don't see a reason to mess with it. I didn't need to do the Throttle stop mod on my 99 SS... the Formula needed a little grinding.

You should check the TPS once you "ground" on it.

 

any more opinion's on this part, cause i was looking at it too but didn't know if it was worth the cash <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

 

I heard about this mod a little while ago and never saw anything on it so I didn't ask. now that it has come up again can someone explain why this would be a mod? do out throttle plates not open all the way?

 

I had the throttle body off my 5.3 for some light porting. The throttle did not open all the way. I bent the steel stop tab and ground down the aluminum stop bump. I also had to grind the aluminum area where the steel tab rest when the throttle closes. After I bent it it wouldn't allow the throttle to close fully. It is easy to see when it is in your hand. I ground down the throttle shaft alittle also. I would say that the throttle blades open another 15 degrees or so. Can't say what the power increase is if any. I bypassed the throttle heater too.
