I want to go with the standalone because I have it, if I could get AEM I would, but this was what I have so it is what I am going to have to use. Retail on the autronic is just under 2000, so it was a really good find. I also got the link for my pc and I can see all the maps and the features that it has. I am working on the wiring now, Im hooking it to one of those obd1-obd0 jumper harnesses, just so that I don't have to mess around with the vehicle harness, just make it plug and play. It's coming out really good so far but it is time consuming. but I still have no idea how to tune it, I may have to take it somewhere, like this place a couple states over from me (which I HATE doing since I have done everything else on my car by myself)
As far as the phantom grip thing, it's only about 125-150 depending on the website, so it's alot cheaper than the obx, but its not a "real" LSD, it;s an addon to your stock differential and it has springs and plates or something. Either way I was looking to see if anyone has tried it because I know it's been around for a few years. I'm kinda on a tight budget, but that's life.
