"It has felt down on power ever since. "
Key words above. I really do appreciate the Auto Tune, things stay consistent regardless of temps. Did the tuner enable the accelerator feature? Word has it this is a no no.
If the shop did activate the accelerator feature, they never told me about it. I wish I could have used Auto Tune. The exhaust didn't come with a bung for the O2 sensor and it is a full titanium exhaust system. I wouldn't trust local bike shop to weld on titanium to add a bung. It would have to go to a specialist to weld and even then I'd have to find a titanium bung to fit the O2 sensor. It has been getting down into the high 50's occasionally in the morning. Maybe need to make a run on the way to work one day to see if it is the weather.
BTW, the bike only has 5000 miles on it and the filter was installed back when it had about 1000 miles on it.
