Is 45 to high/normal ??
Had a PC111 and V&H 2&1 installed few months back and popping[!!!] real bad at decel. Some of you might remember my post? Had a chance to take it back to the tuner last week. He reduced the popping consideable. However the first column at zero throttle position is 45 at almost all rpm ranges. Is this normal ?? The tuner commented it was unusual; but every bike different. What do you PC111 experts think? Thanks!!

I had the same problem. Mine stopped popping at 10. I have heard of other people having to go to 15 but 45 seems high. I wonder if you have an exhaust leak or something. If it runs good,,, run it.

Mark, I have tuned plenty of PC USB's and I start at 10, have had some as high as 50. Chances are you have an intake manifold leak or exhaust clamp leak. Be sure that the first column does not go below 1500 rpm. This value should be from 2000-redline. When the throtle is chopped closed it will try to pull air from any small gap it can.
