Rich,
I figured out what your problem is...
You're inside watching TV instead of being outside or in the garage fixing your own stuff.
As for banks, They have a different goal from Bean & Tony. Banks has the goal of finding the maximum power that is useable at all times. They are on what people are buying and modifying, they do research once and market that product. The same powerpack for the OBS 7.3 has been out for the past 10 years. The modifications for the SD 7.3 have stayed the same since released except for the introduction of torque converters, Bighoss, & 6 gun tuners.
While we look at banks and say it's overpriced they have done the scientific research that is the foundation that the guys pushing the envelope are building on. Banks & ATS are 2 of the big names that have done the R&D over the years to develop the products, they were in the industry long before the small guys were. When you have guys who had the choice of a banks or ATS turbo (only choices) for their IDI 7.3 or 6.9 and were truely impressed with it when they update their truck they turn around and buy from the guys that have in the past proven to provide what they advertize.
