05 lly weird issue after 4 days

[House]

Have a 05 lly with a dsp5 in it. After a full flash it runs fine for 3-4 days, then seems to get major turbo lag and seems as tunes are 30hp weaker then should be. In ideas? or what to look for?

try logging desired vs actual vain position. some of the earlier models had issues with the turbo vains getting stuck. just a thought
