Hey guys ! I am using the Q 45 TB and am having a problem trying to figure out where my TPS should read at idle. Currently I am at .28 volts. I know when i had my old TPS I was reading closer to .4 volts at idle. I read X-Man's post about install (which is exactly how i did it) and he says that his reading was at .385. Does anyone know if that is at idle? I am thinking that this is also contributing to my "dead spot" in the TPS. I will be giving it constant throttle and all of a sudden my car feels like it hits a damn brick wall.

Also, this question is related to the maft-pro but does anyone know what size setting the throttle body should be using the Q45 with the maft-pro? Stock is 6 and now I am using 9.....is that too much?

As long as the TPS has resistance between the two lower terminals when the throttle body is closed, and when you place a .9mm shim between the stop and the throttle to mimic having the throttle cracked, there shoudl be an overload of resistance.

Not volts.
