I used the TS Module & happy. There are not that many Tuners that fit /work with Int 365 engine. The TS module is not really a Tuner, boosts Fuel rail pressure.
RVS Camera system with Side Cameras work well...you'll need a couple adaptors to retro fit from the Voyager to RVS... also it's easiest to just pick up a signal off you Blinkers. I tried to tap into the Harness at the Steering column & had issues. Road King....I tried to find the part # & RK customer help was not helpful either. I have a old front shock I kept to get measurements from...just need to get a axle weight so RK could valve the shock & build accordingly.
If you have the original EGR Cooler, check it out. The EGR is what caused all the issues on Ford 6.0 engine , International also put a Coolant Filter on their Engines that Ford never did. Have fun!
