Default My 05 GXP on the Dyno
Got my car tuned today, 261whp 266wtq on a mustang dyno.
Here's one video, uploading others now

If anyone can identify the noise my car makes during the slowdown it would be great, can barely be heard in the video tho.

Nice numbers. Are you talking about the squeak when you let off? Sounds like belt squeak to me...

Your car sounds amazing. I'm not calling you a liar but a 107 trap with that power to weigh is kinda hard to believe. Can you post the time slip?

Those SCC springs must really make a difference
The only mod I have over you is rockers. I won't come close to 107.

never heard of this before, although it very well could be.

I have no other idea, but it's definitely not the belt. Slippage would be as soon as you let off and it would be constant if you just had a squeaky belt.
