TPS voltage issues

I have a LS1 from a 2000 Pontiac trans am swapped into my Nissan and I am having an issue with the TPS voltage range.

Completely closed idle voltage ~.503
WOT (fully opened by hand) 4.343
input voltage 5.03 volts

I have a drive by cable 95mm Holley efi throttle body and it will not physically open any more. I have read that my voltage for WOT should be somewhere around 4.65, how do I get my WOT voltage up another .3 volts? Is this something that can be done with tuning?

Why are you repeat-posting this issue? You're getting good responses in the original post......

I thought it may be better in the other section because I’m not sure this has anything to do with pcm diagnostics or tuning. I couldn’t figure out how to delete it

Look at the little buttons at the lower right corner of any of your posts. Hit Edit and go from there.

Do you have OEM EFI or a Holley ECU?
