A concern after Superchip install
First let me say that I love my Superchip. I have only had it in for 30 miles but shifts are alot firmer and throttle response is stronger.I don't think I have a direct problem with my Superchip but this never happened until I installed it. When I punch the throttle from a dead stop and truck is shifting really hard there is a squeak or squeal (no it's not the tires, I wish) Kinda sounds like belts slipping? I never heard this noise before I installed the chip. Truck only has 2000 miles on it , anyone have any ideas? I do love the chip but am concerned about the noise. Thanks

Ditto, had the same problem. Mine was O.K. when I put the SuperChip in but when I installed the shift kit the same thing happened. Just (last week) installed the Gatorback and it went away.

Hi Orlando,
This is typical belt slippage that you will get just at the full-throttle 1-2 upshift, and can happen even in bone-stock vehicles, or anytime you do something to quicken and/or firm up the shifts in the automatics. The quicker shift causes the low-quality serpentine belt to lose traction on the pulleys (it has nothing to do with timing).
This is easily cured by putting a good quality serpentine belt on, and we use the Goodyear Gatorback belts for this. They are much better quality than the factory belt and will immediately eliminate that sound you're getting.
The factory serpentine belt will last a long time before the ribs actually crack on the backside of the belt, the normal wear indicator most look at, but in reality it's a poor quality belt in terms of how much actual grip it has on the pulleys. Anytime you do something to firm and/or quicken up the sloppy shifting in these automatics, you'll get that belt slippage, and the nasty-sounding but harmless "shreak" that comes with it.
This also happens in a number of these vehicles even in bone-stock condition, one of our F-150's did that before the first modification.
Veyr simple solution, & if you like, we can supply that Gatorback belt for you as well, we keep those in stock for this very reason. We also use the Gatorback belts for the blower belt on the supercharged Lightnings & '02 Harleys, as once again it has much better grip on the pulleys and thus you get a bit more boost from the supercharger on those vehicles.

Hi Orlando,
Nope, not serious at all, but it can be a bit disconcerting at first until you know what it is, as it is a noticeable noise.
The Gatorback belt will eliminate that, where another new factory belt usually won't.
Have fun!
