yea i had to reset my windows, alarm beep, radio and clock this weekend after doing intakes... not a big deal. I might get a tender though since they are pretty damn cheap and my battery is getting on in age.
no tune yet... but that's also good to know that the tune may reset since i was considering it next year.
