Of course you can do that. Hell the TSP map is mostly stockish on map 1. But leaving the tune in place when headed to the dealership is a horrible idea. There is always a chance they wish to update the ECU. Good luck explaining why you don't want them to do so.I wish Hondata did have better and faster support. It's not a bad product by any means. But CS is very slow for the most part. It often takes days to get a response at their user forums.
Honestly customer service puts Ktuner over the top. JR is here everyday and replies to all my many PM's.
Off subject a bit but I had an idea on a new on the fly setup. Couldn't we just do the factory boost on tune 1 and use 2 and 3 for the performance tunes? That way maybe you could just go to the dealer without completely reverting to stock.
