I just joined yesterday after a suggestion from Maddog over at Ramforum.com. I hope this site is laid out about the same because it is so much easier to navigate that the Z. I literally spend a couple hours every morning perusing that site because there's always a lot going on. The Synthetic oil thread is the best. Just bought my Challenger back in December with 30K on her. I haven't done much with her other than switch her over to Redline 5W30 and Redline 75W90 in the diff. Would love to buy an unlocked PCM and get a custom tune and more especially turn off the MDS.
