    I purchased the SBD kit with OFT tuner in January 2016. After 11k miles of driving I can say this is a great kit. There are few things missing that are needed (STI PCV valve) vacuum hose and tee for the BOV, and three rolls of exhaust rap, (the stuff in the kit is horrible). With exhaust I was able to break 300whp and my car went from 15.4 to 12.95 in the 1/4 mile. I have also gone from avg 29mpg to 28mpg. I also highly recommend at least 5w-30 oil and change it every 3k miles. I will NEVER go back to N/A
