31248 is the OEM All Countries map for the GT, vin after AV5456. You can only get this in the app. Penner maps are only on the Tuneecu.net site in the custom 3/4 cylinder maps. Not available in the app. However, these are based on the US market tune. You need to copy the tables from this Penner tune into the stock 31248. I assume you raised the speed limit in the stock 31248 tune?
