What type of meeter were you using ? Analog meters will pull the circuit down too much.
The TPS is a 0-5V signal. I use only digital meters and have not seen an issue.
The draw from the LEDs should be small enough not to pull.the circuit out of range.
Cheap digital meters can be found for under $30.
Hack out the display and mount it to the dash. A 12V to mater battery voltage converter willl keep you from having to turn it off and change batteries often.
A voltage regulator such as a 75XX from Radio Shack will run <$5
Have fun :-)
