The only way to be completely sure, that you have enough TPS voltage is too set it high enough to set a code 21, and then back down just below that point, or to call your chip guy, and find out what he's set the PE vs TPS setting to, to max out the fueling correction.
I have a rather large collection of .bin files, and went through most all of them today, and found ONE, that used the 100% entry to max out the fueling. There maybe others, cut all it takes is one to force the above statement, to be universally true.
There are several other entries that can taylor the TPS rate of change, which sets where the TPS registers being 100%, so without knowing that correction, there is no pat answer for what TPS voltage will guarantee pegging the fuel correction. It is possible to set the 100% TPS reading to be about 4.95v, in the code. It wouldn't make sense, IMO, to do that, to max the fueling, but like so many other things, what one tuner likes, is what he likes, so he'll do it his way.
For those of you lucky enough to own a Lockers, it displays the calculated percentage of TPS, so you don't have to guess if your at *full fueling*.
You also need to verify that you're in fact pegging the gm/sec, to the max reading. Some calibrations only read to 235, so again you need to know what's inside your chip.
Now for the kicker:
Depending on another table, there's a percent increase in PE fuel, that's by RPM. So while *some one* might be running at a max TPS of only 3.6, he still might be getting enough addition fueling correction from that table to compensate for an low TPS setting.
