The problem with the hack is the fact it that does not retard the timing on the car and the way in which it adds fuel is not the best either. People have problems at half throttle, full throttle, idle and engines running lots of timing...

That is not to say that there are not people who are using it without any problems though, i researched it, spent hours learning about it and certainly would not use it

I suggest you read this thread here.

For the price that it costs to set it up, you would be better off using that money towards something like a Microtech etc.
