I could literally hear the belt slipping when starting out in the lower gears .
I had a PK2360 belt with 130mm and 79mm pulleys, i went to PK2330 continental serpentine belt and I feel that there's much less slip.

I feel that the gatorback belt is just a belt used to eliminate noise.

I just can't stand that we have to pay this much money for a "respectable" kit and worry this much about shit like this. I also have the small injectors and after i perform some maintenance on my engine I will go test the car on the dyno to see if i'm leaning out.
