i looked in the tech board and it said it should be between 0.54+/-0.075 am i reading that wrong or is that a large gap?and does that mean that anywhere in between is fine or is there a "sweet spot" to set it at?

 

it means the voltage can be between .54-.075 volts and .54+.075 volts.

 

I always shoot for .55v.

 

does a higher setting make for better response?

 

Not that i'm aware of. .55 is supposed to be throttle blades closed.

 

You can go as high as .56 and yes it will make the response a little crisper....but go to far and you will create a bogging issue.

 

Well one day I was adjusting my tps switch with the motor ideling. I was going to put the voltage up around .60 volts. It just so happened that while I was adjusting it the motor seemed to idle the best at .54 volts so that is where I left it.

 

Just a note, an article in High Performance Pontiac (Feb. 07) had an idle mischief article which included TPS voltage settings and it states that MAF cars should be set to 0.54 Vdc (0.465 - 0.615 Vdc) and Speed Density should be set to 0.71 Vdc (0.660 - 0.710 Vdc). Try getting closest to the middle values.
