Default Tps noise

So after installing my new motor and getting it tuned im coming across noise in the tps, map and clt sensors. tps is the wost of the bunch. i dont think it was a problem before but it is now. Iv got a 1710 box and i think its rev c i forget.

Any tips on reducing the noise? at closed throttle tps fluctuates very fast from .7% to about 1.5% is this normal?

Iv verified its not a bad tps with another unit and iv checked the ground at the tb and the ppf they are clean and good.

I hacked a bunch of AEM series 1 boxes to reduce the noise in all the analog inputs.

You can get by without the hack... just make sure the TPS reading never goes to zero.

Hacks are pretty invovled. I've documented them so that I can repeat them, but not in a manner that someone else could do them.

Here's one set of data showing improvement
