I took my new to me 09 coupe to XP Racing in Oklahoma City for a dyno run this weekend. My plan was to just baseline the car and see what kind of horsepower it was making. I was very impressed with the owner's (Brett Seaberg) vette knowledge once I was there and decided to let him tune it. I was very happy with the results so I thought I'd share them here. I highly recommend Brett if anyone in the region is looking for a tune. He knows what he's doing and the price was very reasonable IMO.
The only mod on the car is a K&N intake installed by the previous owner and NPP exhaust from the factory.
The car made 390hp on the first run and just shy of 409hp after the tune. Results are below.
