Install is a headache. 5 hours /$500 total sounds fair. $1000 is not.

Best of luck and please post your results for others.
Wow thanks for the info. Yes the shop pulled the part number off of the existing cutouts and confirmed they are actually Summit Racing cutouts, but I found the QTP model that would go with this system. I was hoping the install wouldn't be too bad since all of the wiring is already in place, and the shop did confirm power and signal were not a problem. When I asked if I supplied the cutout parts how much they would charge, they said probably $300-400 as they estimated it based on a 3-4 hour job. That doesn't seem too bad.

When you say they need regular service, what would that entail? Is that something I'd need a shop to do or that I can do myself?
