I've purchased two Marty tunes and put 4.10's in two Crown Vics (and a 5-speed in one of them). He's awesome to deal with but I think I'll just do it all at once and save the $150 revision fee.

Glad to hear you got it all figured out. I never had my MM tuned before I swapped out the 3.55 for the 4.10, so I don't know what the difference is between the factory 3.55 tune and a custom 3.55 tune; I do have a custom 3.55 tune loaded on my SCT though...lol. I just remember that after I had the 4.10 installed and the tune loaded I was able to chirp the tires on the 1-2 shift, which I had never been able to do before so I was all hyped about that.
Congrats again on your 'new' MM and hope you enjoy cruising around in it!
