Hello, my name is Brian Harris and I have been modifying fuel injected vehicles since 1995 and moved to programming the fuel injection since 1999. I have been posting recommended engine modifications for good streetable fuel injected engine since 2003. I ran tbichips.com, tpichips.com and later harrishighperformance.com. I finally decided to combine all 3 into one site. There is a menu link for TBICHIPS, TPICHIPS and 1996+ OBD2 to keep all the content similar to what I always had without having to maintain 3 separate sites.
