That is way too much. Mine was done for less but I am not on the east coast. Good luck, I am sure you can find someone for at least half that amount in labor.
don't be sad if it's not everything you want it to be as soon as you drive it. Kill the nannies, launch it a few times and let it learn. It only gets better.Once you get past sticker shock you will be fine . Mine is being installed today. It is crazy how big and heavy the blower is.
I got mine installed for $1000 in 2009 by a dealer outside of Phila PA
