Thank you for the reply. Mine isn't flooding, it is vapor locking and lean. The only saw in use the decomp on is my ported 371xp, and only because 71cc at 190psi is hard to pull over without it. I talked to an upper level Husqvarna support person at corporate and told him what it's doing. He said it's not right, gave me a reference number and is having me take it to my local dealer. Yes, they have the auto tune software. Thanks, Mike
