Dyno Day!!!

Went out and got my 2011 Storm Dyno'd over the weekend. Nice little performance gain, smoother throttle, and some of the popping on decel from the cat delete is gone.

Quick video of the final run: www.youtube.com/watch?v=z-3OY7EflQ4&

If you’re interested and haven’t already done this, use the power commander software to read the tune in your ecu and save it to your computer. Look at the numbers in the first column (zero throttle). Adding fuel in this column gets rid of popping on decel. If it’s still popping, you can try adding more. Start above the idle rpm, like 5% at 1500, 10 at 2000 and 15 up to about 4000, in the area where you have popping. There should be positive trims in this area if you’ve opened up the exhaust as this creates a lean condition which caused the popping in the exhaust. Save the modified map(s) to the computer and load into the PCV. You can always reload the original map.

Thanks but I don't have a PC. Just used TuneECU and adjusted the map based on the dyno results.
