Default Firmware update order and other questions - 05-06-2019, 06:27 PM

In the Ford 3.5 EB sticky fire are updates, there are three. Do I need to do them all in order or will just loading the latest #3 give me everything in 1&2 as well? I have loaded #3 successfully.
I have a 2018 Raptor with a Roush CAI and the JB4 with the connect kit. I have changed the plugs to the Motorcraft SP542 iridium (cooler) plug to handle the CAI and the tuner. I run only 93 octane gas. When the JB4 is not on, the throttle seems fine, when JB 4 is on Map 1,2 or 3 the throttle seems to fall flat initially and then come in strong, does the same when in sport mode when in throttle, off and back on. Suggestions? Many thanks

Hi Payam

I waited to respond as was having truck in for service and some harsh shifting concerns in sport mode. The dealer did a transmission reprogram (TSB 18-2274), and it appears to have made the throttle more responsive and the shifts faster, seems to have corrected the problem of the stumbling that I alluded to in my original. Thanks
