Installing A Timbo's APPS Sensor What's needed?   -Timbo Apps   - 10MM socket and wrench - T20 torx - Paperclip - Mutlimeter     Timbo gave me a Timbo APPS sensor to install on my truck and try out. So I'll tell this much its built much better than the factory ~$450 dollar Dodge stock APPS sensor! I will say it works with the exhaust brake and is high idle ready with no compatibility issues. Timbo APPS sensor has no effect on these options
