I am adding a
90 DAY MONEY BACK SATISFACTION GUARANTEE
Not sure if the F1 is worth it? If you do not love the way it shifts, send it back and I will convert it back to stock and ship it back to you. AND I will refund every dollar you paid to me, including my return shipping routes. Please give the TCU 400 miles to learn the new mechanical properties of the valve body. It can behave awfully weird after the big change until it figures itself out.
What other major mechanical Subaru upgrade comes with a satisfaction guarantee? Seriously, I want the list so I can compare notes and do better.
