Great high-end power and plenty of torque through the prime driving range. Best gains: +92 hp and +219 lb-ft (rear wheel). Safe EGTs; more fuel economy.
8.3L ISC PUSHER: Banks Stinger adds +92hp @2200 rpm, right where you're looking for high-end speed. But, the power you really feel is torque, and Banks Stinger matches the peak torque output of the stock engine (1050 lb-ft @ 1400 rpm), and holds that level through the prime driving range, with a top gain of 219 lb-ft @ 2200 rpm. Banks' method puts out significant muscle for Cummins ISC 24-valve motorhomes with standard auto transmissions, without challenging the unit's durability. Stinger's BigHead actuator gets the factory-turbo "on boost" faster and holds on to it, while the OttoMind precisely calibrates fuel for more power and safe EGTs.

It's an old episode but what Gale explains about the principles of improving the performance in your RV still applies today.
“If you're ever crossing a mountain pass and you can't seem to keep up with the pickup or RV in front of you, chances are good you're following a Banks-equipped truck.”
