It still hasn't came in yet; the guy promised it would be here Monday through Wednesday. I went ahead and just ordered the 52001 because it was over a $100 cheaper and update-able for the 3.7L. With the spare $100 I can use it for a 2'' lift or Flow master ^^
p.s. I found that you can buy them on Ebay for DIRT DIRT cheap but you must ask if it has been "Factory reset" or you will be screwed ion the end!
