Mike I have a question for you. If you are updating the handheld and dont return vehicle back to stock will you loose those settings or file?

Sorry for the hijack but think the question belongs here too.

Will the handheld ever be able to do data logging if you dont have a laptop?

Mike question:

07 R/T 5.7

Are these good settings with just a CAI, 180 Stat and Catback? Using 93+CAI tune
