Is MAF tuning anything like LV8 in '165 TPI???
Can you elaborate...are you using a cable drive from the 4L60E to drive the stock speedo? The stock speedo can provide a 2k pulse signal but Idk if the LT1 PCM can use it. '7730 you can uncheck mag sensor. If anything the PCM is probably looking for the 40 tooth reluctor pulse per mile. Someone correct me if I have this all wrong. Oh are you using both in the same tailhousing???
