Lol that's my kinda luck and your right... turbo is like nitrious so many variables some peoples car make like 300 on 13 to 15 psi while mine makes well over 500 or like the 1/4 mile calculator works some people have 800hp and run tens while others have 500 running well into the tens its all like a puzzle and you got to have all the pieces that fit together to have the perfect picture in the end
