Hey everyone. Just getting ready to upgrade my stock 03 2500 HD. Once I get the injectors serviced, I wanted to install and Edge Juice w/ Attitude monitor, 4" exhaust and AFE intake kit. My problem is, I bought an Edge Juice on EBAY (new one) and I got one for the LLY instead of the LB7. Does anyone know if the LLY Juice will work on the LB7 too? The manual says LB7 and LLY on the cover, but doesn't say if it will actually work on the LB7. The part # is EJC1000AWAM. Any help would be GREATLY appreciated!
