Well I am new to this site and I see that you are a senior member, thats why I am contacting you. For 1 year I have been researching my 05 mustang gt automatic, and have not gotten clear real world answers, on rwhp limitations on my automatic. I have received nothing more than conflicting information from sites like kenne bell, brenspeed, etc. especially have to do with bottom end hp limitations without forging and still maintaining everyday driveability. Now that I am living in Mass. I have emissions to deal with. The questions I have, are canned tunes like from saleen, whipple or roush, the best way to go if i have to get my car repaired, because if a ford dealership can't recognize a custom tune, therefore setting it back to stock, in theory wouldn't I have to go back to my tuner to have them reinstall it? Again I glad I am part of this website, I still have to many questions.
Best regards
Mike
