for checking the tps sensor what should the voltage be at WOT?

 

4.3-4.7 V. It will vary depending on your closed throttle TPS voltage but should be ~ 4V higher than your closed TPS voltage.

 

i check my voltage its at 4.38 volts at WOT, so thats within specs?, reason why iam asking is because my car wont downshift in second gear when iam crusing 45 mph or faster at WOT, and i just got the LS1 edit tables all installed by finish line performance and they say its not the program that the program is all set corrrectly, they say it can be tps voltage at WOT or something

 

4.38V is good.

The car won't downshift into 2nd gear from 3rd gear at 45 mph, or won't downshift from second to first at 45 mph? Your wording was a little unclear. What year and rearend ratio?

 

my car is a 2000 camaro z28 with an A4 trans, i have 373 gears and when i floor my car at WOT 40 miles per hour i get that screaming performace it downshifts, now when iam crusing at 45 mph or faster and when i floor my car at WOT i dont get that screaming performance, it goes but it crawls, i got ls1 edit on my car and all the tables were tuned at finish line performace, or is that normal for a 373 gear not to downshift for that screaming performace like that when iam crusing 45 mph or faster?? this is my first A4 car with 373 gears, i know that my 273 gears always had that screaming performace at WOT at any speeds when iam crusing, anyone here with 373 gears do you guys still have the screaming performance at wot at speeds of 40mph or faster?

 

Hit it let up quick and hit it again it'll drop another gear.

 

i dont understand, what do you mean?

 

Stomp the go pedal then let up and stomp it agian real fast.
