I’m not sure of tuner or software; but I know I performed a drain & fill on mine every 10k miles (that’s after my 1st 50k flush) & it seemed to quicken up each time-like a tuneup.
Also try calling up Pat@Levelten Transmission’s (973)828-1000 as he should know.
No jabs from me, loved it & ran a best 1/4mile 12.98@106.62
