Throttle Body Enhancer Did anyone read or have the article that was in Chevy Performance Magazine that talked about building your own plug and play TB enhancer? Casper Electronics sells the connectors for it and refrenced that article to build the electronics. The connectors are $20 but the actual unit built by them is $90. I would rather build it. Thanks
Re: Throttle Body Enhancer The Casper's TPS-TEC doesn't really do anything to improve performance- all it does is fool the PCM into thinking your at WOT at any throttle position over 80%. You can accomplish the same thing by pushing your foot to the floor, and that's free! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

There are some "chips" sold for European and maybe Japanese engines which do no more than that. With throttle-by-wire it's easy.I'm not sure how you do it with mechanical linkage.
If the very old days (60s and 70s) some OEM's designed their accelerator pedal geometry to open the carb butterflies fast initially so the car felt like it had more initial "power", and cruise required only 10-15% pedal travel.

Re: Throttle Body Enhancer Old SStroker- you got it right. All the TPS-TEC does is improve throttle response, and even that effect is minimal. By the time your at 80% throttle, you're probably headed to WOT, anyway! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> I had a TPS-TEC on my Buick Grand National, and it was somewhat useful on those cars for a couple reasons: they had a tendency not to go to full TPS voltage at WOT, and it got you into the boost a little bit sooner.
