I don't know what I should put on it to make it have more take off power. I was thinking maybe a new rear diferantial but I don't know what im talking about.

 

You don't have a rear differential if you have front-wheel drive. The differential is in the transmission on front-wheel drive. And even if you had all-wheel drive (4X4) you still couldn't change it without changing the front to match.

 

A little supercharger might help - but I don't know if the engine or transmission would handle it very well.

 

Our cars are made so your mother or you can find it satisfactory in Minn where it gets far below zero or Texass where it gets 130! It can run on very good or poor fuel etc.If you want maz milage it's different ,if top speed we need to find a shop that can make our cars suit US! A chip will do a lot but there's physical things also.
Next question: which is the BEST CHIP?
