2013 GT Manual - My GT500 muffler dyno vs stock, no other mods

I can't believe my windshield washer fluid change did not show 1-3 rwhp on the dyno....

They did their baseline in 4th gear to show the 10hp gain in that video. Baseline run starts at 0:14 and goes to 0:19, 5 seconds. Run #2(stock tune and RPM) starts at 0:43http://www.youtube.com/watch?v=KqVh5sAgvJo&feature=player_embedded# and goes to 0:51http://www.youtube.com/watch?v=KqVh5sAgvJo&feature=player_embedded#, 8 seconds. Run #3(higher redline) was from 1:08http://www.youtube.com/watch?v=KqVh5sAgvJo&feature=player_embedded# to 1:18http://www.youtube.com/watch?v=KqVh5sAgvJo&feature=player_embedded#(9) or about 10 seconds.

We did all three pulls in 5th gear. There is another thread where that video has been posted. I have gone over this a few times as well.

This is my personal car. They did not do any of the tuning. We only used their dyno since they are close to our office.

Run 1 was done a 9:41 am, Run 2 was 11:04 am, and Run 3 was 12:02 pm.

The HP difference in mufflers came out of left field for me. I did not expect to see a difference in the 2 runs. I still have a hard time believing the HP gains, but no 4th gear pull was done to make that number. The cool down time in between the 2 runs leads be to believe the difference honestly.

I was expecting them to make 0 power. I don't go around bragging my car made 9rwhp with just an axle back. I know better than that.

It's a part of that video, and even the dyno graph that I can not change. The GT500 axle back is probably the most popular axle back to this day, and we did not "make" up that number just so we could sell more of them.

Not trying to sound like a dick or anything, I just want to clear the air about this subject.
