I would highly advise against it. There are much better options even though they cost a lot more up front. However, in the long run, an SCT tuner with custom written tunes and a set of gauges or edge cts monitor will be best. The edge juice with attitude, old ones at least, are notorious for destroying transmissions. They don't tune the tranny at all which is bad when you add more power. I can speak from experience that the edge juice I had caused a flair between my 3-5 shift which I did not have prior.
