How many volts for TPS at WOT on an '85 L-98?

I did the idle air set, volts .54, and checked volts at WOT. I'm between 4.2 and 4.3. Is this sufficient or am I missing out on some fun?

Re: Throttle linkage on '85? (MrNuke)

More battle tonite, same result. This throttle body was 'reconditioned' and I ground down the screw they used for the shaft on the TPS side of the TB. I thought that might be the hangup. Not.

Re: High idle - '85 L-98, need help (65Z01)

I thouroughly agree about the 'false' air. I'm going back out to the battle field (aka garage) to check. I also remember hearing a little 'hissing' so I'm going to look for a possible vacuum leak.
