I have had a .5 sec power loss when I have been cruising around. :dunno It usually happens when it reving around 5-7K. It seems to be fine with some revs. The only performance mod I have so far is a Powercommander. I also have a speed healer That I have the jumper on. It kept wigging out on me when it got hot. I currently have the Stock Bike Map that Dynojet gives you with the PC. Has anyone else had this problem???

Here is LOTS of reading for you on that one...

To get to the part where it says there are 2 new versions of the TPS, look around pages 28-33. Sorry it had to start happening to you too.
