    Ive made some progress, but still running into idle issues. Latest tune attached and updated comments in this thread. See the oscillation at idle? Im guessing its either tune or MAF turbulence. Any ideas?

    How is the MAF mounted? As in where is it mounted in the air stream?

    Turns out a failing MAF. Bad injector data, and turbulence sent me on a wild goose chase. All good new and I'm tuning the MAF!
