There is nothing wrong with Dinan. I have gotten great service out of them but my 335 had the software already loaded on it when I bought it. I don't know that I would have paid the money for it.
They do stand behind their product. I have seen them pay for whole engines at my local dealership, if needed.
I still don't think these cars need more power. They can;t put what they have down to the ground with r-comps on corner exit without a slow roll of the throttle. I would spend the money on some coilovers and camber adjustment before added move power. Even from a roll the fat ole Cameros are going to pull you after you up the boost. They will not out brake you or out turn you....
