Hello all. This is my first post, so forgive me for asking a question that has probably been answered several times.

I just upgraded my evo to a gryphon. Are there any issues with running the custom 87 performance tune as my daily driver?

I have an '07 supercrew with 5.4, volant cai, and roush cat-back. I drive about 25 miles per day, mostly city.

Thanks for your input.
