Yeah it sounds really good, and they even say that the New cat isnt even ready yet, so they are trying to sell you the HAFC setup and getting yo all hyped up for when they come out with the PICC.
From the website, and in the email saying id get my price quote in a few days, heres is one of my favorite parts.
"We are also working on a very unique financing program for the PICC upgrade. Having a PICC is expected to greatly increase the value of your car. So much so, that the car itself could be the collateral for a loan to buy the PICC. All you may need is the title and no matter what your credit is like, you will be accepted for that loan. If your car is still being financed, this funder would just refinance it with the PICC on it. The payments should be less than half the amount of the monthly savings."
That right there tells you it is going to be very expensive, which is one reason why i kinds believe it possible that this would work. The OEM's know how to drastically improve MPG on all cars and trucks, but the technology is very expensive, and none of us want to pay for it, and if they put it on all the cars they sell, well they wouldnt sell very many and go out of business. And the BS CAFE standards wont help.
The covalizer thing sounds like they want you to keep buying an additive you have to put in your gas every fill up, which means they get to keep sticking it to you.
