Ok, has anyone flashed their 250 sho on a PHX921 ??
If so what are your speeds ,hole shot and,etc?
Search for "falconpilot" and look at his posts from a year or so ago. He flashed a 20PHX/SHO and did some other mods to get all he could out of it. Haven't seen anyone that has admitted flashing a 21PHX/SHO.
