Rear gears - 4.10's vs 3.73's

WTH?! How come my MM claims premium only and yours doesn't!?

Stryker does not have a marauder. He has crown vic, that's why he runs regular gas.

@ GreekGod: Of course, you are correct. If a moron tunes your car on a dyno, you're going to get a crap tune. My comment about a dyno tune being better than a canned tune was predicated on the dyno operator being a skilled tuner having experience with the car in question, like Lidio, Jeff at Mo's, etc.

ANY tune is a compromise! Is a dyno tune "better" if some idiot dyno tuner screws up and you puke an engine? Lidios tune is proven safe. Timing, shift points, fuel map, real road driveability, weather adjustments, and who knows what else all contribute to a real world tune.

Putting a car on a dyno, and loading the engine and transmission for various conditions, such as uphill, downhill, idle, idle to wide open throttle, cruising, tip -in, 1000 to 4000 rpm part throttle acceleration, is the true test of a tune. Ford has $million dynos for doing that, not some "cheap" $20,000 dyno.

I'm not saying Joe Blow can't do a good job, but it takes skills.
