Diff fluid makes car feel slower

You'll be fine. Take out your rear seat then the car will make all sorts of new noises and it will feel faster again

That's racecar status.

If it's stock, most definitely.

Not stock at all, but not stupid loud.

I have 75w140 from OP and my car is not slower.

I may have found what the issue was. There's a vacuum line on the bottom of the steeda CAI, that's no longer used when you install a GT350 mani. Looks the plug I had placed in it, popped out(the engine didn't suck it in). It's a decent size line, so I'm sure it was throwing the AFR all over the place. I wouldn't have found it if hadn't been installing a thermostat tonight. Will report back tomorrow.

Clearly those people don't understand how cars make power.:lol:

I understand it fine. But I don't think you can feel less than a 5% power change driving on the street. At the track yes, driving to work, no.

I feel my car is slower since I gained 20 lbs. of "I hate my job but it pays for the Mustang" weight...
