Dont bother with a mail order chip. I tried brain and TBI chips and am very dispointed at what he got me. He is a great guy and got it running decent but not great. Invest your money into a wideband 02 sensor and do the tuning yourself. people on thirdgen.org know alot about TBI and what it can do. Stock injectors will not be nearly enough on the high end. I would recommend something more like a 80 lb at 14 psi. The stock injectors are 50lb not 65. 65s were in the cop 350s, Also offered in the holley unit. The holley unit will require alot more programming in the cold loop to get it to run right. You need to play around with the fuel mapping alot.
