Congrats, get a hold of me if you have any questions about the stage 2 pcm tune by Whipple. I had the 8.2 mag which was 380hp stock and gained around 85hp off the tune. Went from 68mph to 78mph.

Does the Stage 2 tune require premium gas? Any other issues / concerns with the tune?

It would have to wait until next year when the 1 year warranty expires.

Yes it requires atleast 91 octane. And good idea to wait on the warranty.

Did the picture turn out ok?

I'm playing with links direct to google photos - I have a strong dislike for photobucket. . .

Its sized for 800 pixels - looks good on my laptop, but its a 3200 x 1800 display - so the pic may be a little large for some?
