Belt squeak

[DailyRam]

Ever since putting a custom tune on my truck, when I run it all the way out, WOT, just before it shifts from 1st to 2nd there is a squeak/chirp. Not from the tires. I think it is a belt. The truck has 60k miles, I bought it with 45. The belt looks fine, but should I be concerned and have it looked at or is this something that happens when shifting above 6k?

Don't worry,it happens to most of us that run them hard and shift above 6,000. My 14's been doing it since I tuned it when it was new,and I now have 35,000 on it,and about 400 dragstrip passes

Go buy a Gates Fleetrunner belt. It will stop the squealing.
