Fill in a Spreadsheet with Data

Hello, My name is Connor, I require a freelancer to carry out some research for me, I need someone who knows about cars and car tuning in particular. I need to know what modifications are required to take a car through the tuning stages (Stage 1, Stage 1+, stage 2, stage 2+ and stage 3) and what the respective horsepower increase will be from stock specification... please research and understand what these stages mean first. I have attached a spreadsheet showing a few example of what I am looking for and a table that i would like to be filled out accordingly. Please if you are unsure of what I am asking; ask me so we can clear it up. I will check at random several of the bits of data you have entered to ensure it is legit and not made up random figures. If successful there is a very high chance I will rehire as I will continuously be needing new data.
