Barry, <div>
</div><div>I have the same issue with mine.  Spool up time from idle to WOT (10secs), other than that works great...  from 1/4 to 100% power though it spools up in about 2-3 secs.  Pump is MTH so its the latest...  I havnt been able to figure out any settings that will improve the delay so i try to stay in the 1/3-100% range prior to final approach.  </div><div>
</div><div>I have found that on final approach you need to be very sure before you cut the throttle.  </div><div>
