I am new to this board and have been reading all I can about the setups etc. for Allisons and am trying to squeeze all I can from my Astro. It will have to do till I can round up the money to buy my first Allison!! Anyway, I am sorry for interrupting but I have tried a Trophy, Tempest and TXP. Because my hull is so heavy at 18'8", 1640LB, the Tempest was the best at speed and holding the bow up but a dog out of the hole. the Trophy spun like crazy but could not hold the bow up and was much slower. I was told to try the TXP over on BBC and what a difference. Great out of the hole and almost as fast as the Tempest. 25P Tempest at 6000RPM's at 71.2MPH and the 25P TXP at 5500RPM's at 68.9MPH all GPS. The TXP will be worked by Mark Croxton over on the BBC and was told he is one of the best. I was told this is a general rule to drop down a pitch or two from a Trophy to a TXP. By how much depends on the hull. Hope this helps. :gone fishing
