flow matched means the inj. are tested and matched to w/in 1% of flow rate, which is in my opinion, the correct way to go. There won't be an unbalance between cylinders. I.E. one cylinder running lean or rich over another. You can order the chip for alchy performance in street duty, which is what I did on the 86. Can't beat that combination of 93 and alchy. Allowed me to run as high as 30# on the street. Of course you will have to purchase an alchy kit.
I believe Eric allows a reburn of the chip w/in 1 years time, if you can't afford the alchy kit whenyou order the 60#s and chip you can send it back for the upgrade when you get the alchy kit. He'll correct me if I'm wrong!
