^ this. I can't count how many times I've bought something and replaced it with something better suiting toward my goals.

The yonanka is nice it's quiet but it's got a great tone. Also Ganyon there's no way in hell you got a 12" P3 with a box and a 1000 watt amp and all the wiring for 100 dollars. The sub alone is more than 150 used.

This ^. Take before and after pics. It amazes some people what you can do to a car. If you have the money and there isn't any structural damage definitely go for it.

Could also be your used to a faster car with more power. A car that old definitely needs a tune up however it still won't see great acceleration ...ever. Most especially at 70.

Your deviation from your reading shouldn't change that drastically it should be pretty consistent. Unless your flux capacitor is broken then you may have to alleviate the pressure on the omg valve. Have a buddy do 60 then match his speed and look at the speedo.
