    It all depends on your expectations. If you plan to spend hours and hours of troubleshooting, testing, data logging, and tuning then yea, should be fine. If you are looking for something that works out of the box you will probably be disappointed.

    well, working out of the box is not hot-rodding and takes away all the fun, doesn´t it?

    The reason they say not computer compatible is because it requires tuning. I'd expect that cam to work fine with tuning.

    I ran a cam with a little more duration and it wasn't too bad to tune. Ran on a stock bin but did required tuning to get it right.
