I'm interested in how SVT went from 500 hp in 2007 to 540 in the KR and the 2010, and to 550 in 2011. Were there any internal modifications to the engine, or was it all external? Just a tune? Different pulleys? Anything else? I ask because this seems like a safe guide to a little more hp and tq.
My car sat for a year while we figured out why it wouldn't start. Now the ABS and TC klights are on. I'm thinking it's just a matter of cleaning gthe oxidation from the sensor(s). If so, is there more than one, and where is/are they, and how do I access them?
