Recently got my Megajolt stuff installed. Only took me seven years since I purchased it! Anyway the tps seems to be a bit jittery when the throttle actually changes position. Video below should demonstrate better what I mean. My foot is off the pedal at the start, and each time you see the needle move I'm pushing it slightly down, ending up at the bottom by the end of the video. It seems to get it right, but it wavers all over the place when it's making the transition. Dodgy sensor?

Can someone at least tell me if this behaviour is normal or not?
