I am taking the plunge and ordered one. I was concerned about long term durability and the actual fitment but decided that with the 30 day shipping only returns, I would take the chance. It was either that or try new heads, EFI, or some other more expensive option. My Pontiac 400 has stock #15 heads with 10.5 compression and need to run pump fuel, and lots of it due to living up in the mountains and driving lots of highway miles. She loves driving at 4-5000 feet but can't get her properly tuned down in the valley.
I have downloaded the app to my tablet and have already set up some profiles to try for different types of driving. I'll try to get some before and after info for general performance and mileage. Will let you all know how it works out!
