They have a mode u can run the wide open throttle or the 90 tpas mode which one is everyone using or the tps 90percent of wide open throttle

 

i went with my wot switch, i already had one installed and loomed up. works great

 

tps mode is intended more for ls2 cars for example, with drive by wire throttle body. Just use the WOT switch and note weather you make it a HOT activated switch or a GND activated. either way works just fine all though I find that a ground activated seems to work faster. Just remember neither one will work UNTILL you go into your programmer and tell it weather its hot or gnd activated.

 

Works on my ls1 perfect. To the Op go thru the instructions and it will tell you how to read your tps voltage thru the handheld device. Mine I found out at wide open was 3.9 volts so I set it to 3.5 works great so far just make sure you tie into the correct wire at the pcm and the correct wire at the pcm for the tach. No need to use old tech like a full throttle switch if you don't have to. I know its old reliable but just looks lije crap.

 

I use the tps mode on my 408 D.P set up. Its more efficent then the wot. You can set it a 3/4 throttle so the nitrous doesnt it until the pedal is at least 3/4 way down if you need help let me know ites easy to wire in and set up.
