I'm probably not the best to answer this question fully so someone who has researched/tried this can correct or add anything that else that needs to be said. The main problem that people run into with doing this that you will be pumping the 4 cyl worth of air and only 2 cyl of fuel past the o2 sensor(s) and the computer will read lean and will compensate by dumping extra fuel. Having an aftermarket computer, if you can correct the A/F through your stand alone or piggyback, then you may have a fighting chance at this. The issue here is that you how will you know if you are actually running lean during this because of the false A/F reading you will be getting? Getting up to speed with 4 and then cruising at 2 may be viable if you can work that out.
