Mapping Update for 24-26 350
$24.95Price
If you received 24-26 350 mapping services from us prior to May 19th, 2026, you can send your ECU back to us to receive the most up-to-date mapping. With this updated mapping, the quick shift now works, which is the biggest difference. Power is also improved a bit from 1/4 - 1/2 throttle.
