My brothers girl friend just bought (last week) a brand new 2010 Mustang GT (4.6 300ish hp). I was like you're and idiot. The new V6 has basicly the same power, is cheaper and will get much better fuel milage.
The board price is $250. Installation onto the ecu is $75 or you can do it yourself if you want. Then add $300 for the cable and the single car license. We can also install a base tune for you based on your mods if you dont want the cable or software license.
Considering there were 3 empty bber cans and a 3 unopened I am going to have to guess those were not his intentions. I is often late to work because he is hung over from the night before.
One of our emplyees took the company truck home then thought drinking and driving would be a good idea......we just got this truck like 2 months ago. Had several open cans in the back also.....
The blower fan is to keep the injectors cool(er). Not for any other reason. They just wanted the injectors to last a little longer. You need to look deeper into your problem.
