My question is simply can I upgrade to the 4" Z06 MAF sensor and still use my Transaltor Plus v6.21? Was wondering if version 6.25 is required to run this MAF. I know I need the 3-5 wire adapter as well. I currently am running a 3" Impala sensor and 3" MAF-turbo pipe. Looking to go to 4" to help the LT70 spool a little quicker. Thanks in advance for the help.
