Hey Marshall,
I got a couple questions for you:

1. What is the advantage of getting a tune for 93 octane rather than 87? What kind of increase in power am I looking at? MPG's?

2. How much "stiffer" is shift firmness 3 compared to 2?

3. If I run without a cat, Am I looking at any power increase? MPG's? Is there any gains in doing this with a tune?
Thank you for your time!

1. Couple horsepower. MPG shouldn't be be noticeable.

2. That's hard to describe lol... it's just "stiffer". :)

3. I honestly don't know how the I6s respond to not having cats, powerwise.
