Ok i ordered a new prom for my car thinking that i had a hypertech prom and that i needed to get rid of. I have a thermomaster chip...which obviously isnt the prom...so what the hell did this stupid *** chip replace?...because whatever it was i need it back.

The original owner told me i couldnt run a scanner on the car with the hypertech installed?...he said it wouldnt show any codes or anything

and i think because of this stupid chip, the car is running like ****.

 

nvmmmmmm didnt realize the stock prom rides the hypertech chip as like a piggy back...
