i just purchased a superchips programed about 1000 miles ago. Its a great product but when im hamming from 1-2 i hear a noise not sure whaat it is. i know its not good for the tranny to be hamming all and i usually dont but latley when ever i do hammer, i keep hearing it. At first it sounded like i had something in the bed and it was slaming into the tailgate but that wasnt the case, nothing was in it. Any suggestions to what this noise might be?
