lambda just dropped the stage 2 tune. I can't decide if I want this one or ktuner.

 

From what I have read and seen, the Lambda tune is the only option that has addressed the boost-cut issue. Aside from this, they even offer boost-by-gear control along with a list of other features. This may be the best path forward. I haven’t made the leap yet, but definitely considering this in the near future.
