So I've got a late 99 that I'm doing the ZF6 swap on I currently have a NVK3 PCM, and run a TS chip My question is can I keep my NVK3 PCM and just get the TS reburnt as if I had a DAC3 PCM, I could have used the one from the donor truck but it was early 99 and from what I've been told those wont support the new stuff? And they don't have the umph the late 99's do. Either way I know I was looking at a re-burn of my chip at the least, as far as I understand you can use any of the late PCM's you wish because once you install the chip it takes over anyway..right? Also just getting the chip re-burned would be easy, cheap, and fast because I live about 15 minutes from , Thoroughbred diesel and they can do it while I wait in about 10 minutes to run of the mill DAC3 tunes. Just needing someone with more experience than me to point me straight. TIA!!!
