Boost is boost, there's only one way of putting it, whether it's an older GNX that gets a nice 800HP conversion or if it's a Supra swapped 240, anything can be done and anything can be "tuned".
Remember, to tune is to adapt to the expression of a particular feeling, or the like and to adjust for proper functioning. There are two VERY important things in the definition when used in an automotive term, "like" and "function".
Those are the terms that make your car unique and make it work on the road...what YOU desire in your car is what makes you stand out from the stand out from the crowd but still be able to sit down and talk to whomever about why you choose what you did. What your car NEEDS is what takes your desire and make it a reality with the parts to achieve and surpass a long standing goal or aspiration, what brings the like's into action and makes other people turn into haters on your wall or hitting the like button when you post it up on the chi-town subies pages.
