Computer piggyback kit?

[bdemutis]

I was talking to a guy today at work who owns a tuning shop I was asking how I could do something to a obdi computer he said use a piggyback has any one ever heard of one of these. He said he uses piggybacks all the time when he's tuning 95 Hondas he said he never tuned a truck before but he said the piggyback will work. My question is does any one know if its worth it I already found the computer piggyback he told me its so you can hook a tuner to a obdi computer and it will make the computer think everything is ok but the piggyback is actually telling the car to dump more fuel and so on.

My supercharger has a piggyback module that i can program with a laptop. Its from a company called split second. Its been on there for quite a few years and is completely programable to change a bunch of engine parameters. It was custom tuned before i bought it and i have never messed with it but its pretty seemless and hasnt caused any problems.
I do know that it controls the aux fuel pump and aux injectors so the sc is fed the proper amount of fuel at all times.
