No. "Their" software will not recognize the EFILive custom OS (just like we don't recognize "theirs". Find a tuner that uses a proper product

is there a tuner in the bay area who uses efilive and a dynapack or dynojet

We don't keep track of customers usage intentions (professional or DIY) sorry. If someone can recommend someone please post in here.

I guess the other option could be to update to the 2002 OS (12212156), get the tuner to use his "other tool" to tune. Just make sure they DO NOT use an custom OS or EFILive will not recognize it.

Then when they are done you can full flash the COS and then cal flash the tune from the stock OS.

I bought from a tuner, and he tuned my truck via email. Worked out just fine.
