No Ken, this is not what you think.
So I was wondering, what is in your "tuning bag"? Since I do quite a few tunes throughout the month, I usually carry everything in a soft brief case. This is the inventory in my "tuning bag".
1. Laptop
2. HPTuners Cable
3. Laptop Power Cord
4. Power Inverter
5. AEM Wideband
6. Spare Wideband O2
7. Wrench for O2 Sensor
8. Tuning Tutorials (for quick reference)
9. USB Zip Drive
... by the way, I carry my tuning supplies with me everywhere I go, you never know when you might need it.
HPTuners, better than Roadside Assistance!
