Before you buy
What is in a map pack for GMC?
The original .bin of that software version and a CSV for WinOLS that names its maps, with X/Y axes and factors, in one ZIP by e-mail. Map definitions only, no tuned values.
Which one is mine?
The one whose HW or SW number matches your read. The same car and engine can run other software, and a pack fits only the version it names.
What does it cost?
€54–63, the original .bin included. Card through Stripe, no account, delivered by e-mail. All sales are final: open the pack's page and compare its numbers and its maps before you pay.
