Sorry but your assumption that your converter is cheaper is incorrect...plus a stock 6.0 converter can and does handle 500HP 6.0's so for a 7.3 with stock to stage 1's is more than up to the task...
Your XRTC is also stronger than Ford 6.0L diesel torque converters..if so why do you say this?
The XRTC is not recommended for any competition use, doing burnouts or towing goose neck or fifth wheel trailers weighting over 7000lbs when fully loaded. If you have engine horsepower modifications such as larger fuel injectors, aftermarket add on turbo or larger than O.E.M. turbo charger, or any racing, off road or other competition use of your vehicle we recommend the Eagle Series converters which are full billet, competition and heavy load rated.
NASA payload engineer designing converters...ok ya got me there these are designed just by guys building converters for a living...
Cary,
Ford doesn't recommend using the 6.0 converter for 500 hp or for competition, or for use in the 7.3L either. The reason is because it wasn't designed for it.
I see your willing to promote it and hopefully warranty it for 400 -500 horsepower and for use in a 7.3L. That is fine with us.
"Designed just by guys building converters for a living..." I disagree they are designing anything. What they are doing is modifying another converter that had a designer and patent protection from copying, rather than designing their own converter from scratch.
Reference this PSA thread for 6.0 converter vibration:

We designed the Prowler XRTC to offer a stronger stock replacement converter that won't fly apart and ruin the transmission like the O.E.M. Stock Ford converters can do when they fail catastrophically. The 6.0 and 7.3 O.E.M. converters both can fail catastrophically, fly apart internally like a bomb exploding with metal shrapnel entering the transmission and ruining it.
Stock converters have 3 common failures, one of which is the fly apart that causes the above additional damage to the transmission. Eliminating the fly apart failure and offering a better replacement product than the same converter that just failed, for stock trucks or heavy work trucks was our goal with the Prowler XRTC. The design will handle 400 + hp, up to the weight carrying and tow rating capacities of the 99 up Super Dutys, the F and E 450's and all F150-F350 trucks are rated for. We didn't design or price it for performance use, testing it revealed it will hold more horsepower than stock, and over 400 hp. It's not designed or going to hold up to everyday competition use anymore than a 6.0 converter will, and we don't wish to mislead anyone into thinking it would. We don't recommend using it at 400 + hp for non street legal driving. That should be clear and understandable by all reading. It's also on our website's description of the Prowler XRTC. There isn't anything cheap in high performance, cheap and high performance are complete opposites.
We have the Eagle series for high performance and competition use, it's designed and built for it and for those who are heavy towing over the maximum weight rating. To do those activities, one has to buy products that increase horsepower, many of which offer no warranty. Any converter that is designed and warrantied to handle extra horsepower from products with no warranty themselves, will not be easy or cheap to build or low in cost for buyers. By bridging the gap between $1000 to $1600 converters and $400-$600 modified O.E.M. converters with the Eagle series, we have done what many others tried and couldn't do at all and did it without sacrificing the quality one used to have to spend $1000 and up to have.
