I purchased both a regular pump tune and the E85 and BT tune options and have nothing but good things to say about both processes.
Through both the 93 map revisions and then later the ethanol mix, all of my questions were promptly answered and map revision turnaround was really fast, sometimes even the same day if I sent datalogs early enough in the day.
Stan was great to work with and all of my power goals were accomplished. I'm planning on re-tuning in the near future after I build and add supplemental fueling and I'll be coming back here when I do.
