I would do the chip now and get a Mafterburner later as he's working on some new products. Your going to need a chip if you go F/I anyway to handle larger injectors. The chip will/can do some basic things for you that you can do with the tweecer or mafterburner alone. Raise the rev. limiter, remove torque retards, remove knock sensor at high rpms, change the tip in, etc. Use the mafterburner on top of that to tweak your fuel trims, and if this new one comes out you can control FP and soon hopfully have some electronic timing control.
