I recently had a RR issue so I had to send my PCM to Craig Moates. He informed me that the RR PCM was faulty. He told me that it will be a couple of weeks before he gets in any new PCM's. So it looks like I will have to wait about 2 week or more for my RR PCM to come in. This is not a bash a Craig Moates because his customer support is second to none. He has answered all my questions and usually with in a couple of hours of my post. My question is since I have V1 lashScan Scan and Tune Commercial. Can I still tune my stock PCM. I think the answer is yes but I just want to make sure.
