Question HELP: Disconnect battery after installing Staintune + Evo Race Airflow???

Okay, so. . . I had the dealer put on Staintune and Evo Race Airflow system today, during the 600-mile service on my '06 KS. When I got the bike back, it sounded great, but felt boggy--particularly in the mid-range--and it didn't seem to take off over 7K rpm the way I was expecting.

Before leaving the dealership, I had specifically asked the tech whether he pulled the leads off the battery after seeing something somewhere about needing to reset the ECU after adding pipes and air filters. The tech told me that the ECU automatically adjusts to whatever fuel/air/exhaust setup is on the bike, and does not require a hard reset via unplugging the battery.

What is the common wisdom on this situation? Should I go ahead and pulled the battery leads? If so, for how long?

Thanks in advance for any input; I am really stressed after the disappointing 30-mile ride home tonight :-(

Evo's PDF manual doesn't say anything about hard-resetting the ECU.

Will definitely email them, but hoping to get an answer before I hop on bike to go to work tomorrow, a.m.

Thanks!

I would reset the ecu.. Also it will take about 50-100 miles for the bike to re-learn itself.

Erik,

Thanks for the input. Does the "re-learning" process require any special riding behavior?

I did this when I did my exhaust and it made a noticeable difference. It WAS a full system though. Can't hurt to try it.

Thanks to all who responded.

I disconnected the battery over night, then reconnected and twisted throttle open 3 times after turning on ignition.

And. . .

. . .immediately noticeable improvement. No hesitation or bogging through mid-range. I haven't opened it up beyond 6K rpm yet, but am assuming that improvement will be seen there as well.

Again, thanks!

Interesting... I replaced the garbage can with a Remus Powercone and noticed a bad flat spot on low RPM. I had read not to worry about computer reset. However, after reading your message I can't wait to try. What's up with the three throttle rotation? Sounds like changing my oil in my Avalanche!
