Evan,
The Six-Guns that you have tested are most likely the old calibration. The changes that we made to the calibration were all about improving acceleration, and that would hold true in any acceleration dyno test as well. I’ve talked in other threads about the differences between load testing and acceleration testing, so I won’t go into great detail here, but I can guarantee that you will see a significant difference between the old calibration and the new calibration in an acceleration test. Comparing them in a load test, the change would not be quite as pronounced. You can determine which version of calibration that you have by looking at the clear label on the back side of the module. If it has the number 62976-05E it is the latest calibration, if it says anything other than that, it is an old calibration. The new calibration started shipping around the end of June. If you have the old calibration and would like to have it updated, simply contact our Customer Service Department at (888) 839-5600 and they will make arrangements for you to send the module in. You pay to ship it to us, we pay to ship it back to you, the re-flash is free.

The improvements at the highest settings can be measured on a truck with a stock transmission, that is what acceleration dyno testing (such as your Dynojet) and track testing are all about. It is only full load testing on a dyno that cannot be sustained in the highest settings. Those settings are not recommended for towing, which is the only real world condition that approximates full load dyno testing. If all you are doing is drag racing, then the power available in the highest settings is entirely usable, even with a stock transmission. By the way, for those that do like to tow using their Six-Gun, they may be happier keeping the older calibration. For those that are nervous about using a racing product like the Six-Gun for towing purposes, we still offer our Stinger product, which is a single level of fuel calibration to match added airflow. The idea is that we have products that will suit everyone’s needs.
Catoiler,
Our 235 quad cab dually ran a 20. 86 second ¼ mile with no torque braking and no modifications to improve the truck beyond its basic street configuration. The truck in its same configuration, just adding the Six-Gun (still no torque braking) turned a 17. 38 second ¼ mile. Our 305 test truck was a similar quad-cab dually that was already equipped with a Banks Monster Exhaust, BigHead actuator and a Ram-Air filter. Again with no torque braking and no other modifications, it turned a 17. 82 ¼ mile, improving to 16. 19 with the Six-Gun added. I can’t tell you why your truck was so much quicker except to say, different track, different timing equipment, different driver, etc. The purpose of these tests was not to see how quickly we could do the ¼, but rather to compare products with minimal variables.
