Anyone here use this kit??http://mustangtuning.com/speedcal-410-gear-oil-kit.html Is this all that I am going to need to succesfully get my gears installed with the speedo working correctly? I am almost certain that I do not need a tuner, but any help would be great, Kyle.

What kit?? You will need a tuner since you have an 03 to fix your speedo problem unless you want to have your speedo off.

There is the kit, it comes with a speedo-calibrator, will that not work??

It will as long as you have a manual. But, why not a tuner?

I don't feel like spending the extra 200 bucks right now, I'm planning on doing quite a few things to the car and get it dyno tuned all at once.

Yeah that should be all you need. Im getting the same kit but with the tuner. Its worth the extra $200 if you ask me. The tuner is helpful in alot of ways.

How is the tuner so much more helpful rather than a professional dyno tune??

I Believe you could get more HP out of a good dyno tune, I know a shop in Ga thats known for its great dyno tunes(www.Moldularpowerhouse.com). The only bad thing about dyno tunes is that its usually a little more expensive than a tuner, but I guess its worth the extra HP.

Is this kit come with the bearings I need?? Are there any other stupid things I will need to install them?? Also, does this seem like a good deal?? Thanks, Kyle
