i just had a question, i researched alot of companies and i still can't figure out which company is one of the best to tune my Evo. HKS was one of my first decisions but, just wanted one type of company that provides everything to tune my car because i just wanted to stick with one brand. And any other Evo owners to give me some first perspectives to choose the best company for this car please leave comments thanks.  

HKS PERIOD!
