I bought this car used with 1600 miles on it and when I got it, it was rode hard and put away wet. The car had a 2.9L Whipple with complete supporting mods along with Kooks LTH's, Mid and axle backs. It bucked, surged and loaded up and when you put your foot down it made so much smoke it looked like a diesel pick up... not to mention that it sounded like complete crap.
I replaced the PCM and added another set of Kooks 3" x 10" race mufflers along with a set of cats from Kooks. The car sounded good but the original tune was terrible so I setup a appiontment with Ed Clark to come down and dyno tune the car.
The way I would describe the tune on the car from the previous owner is undrivable. You literary could not drive this around town it was sooo bad! We shortly discovered that the original tune was setting off one of the O2 sensors in limp mode by overalying tunes. In short I learned that tuning these new 2011's is like a whole new world even when compared to the 2010 GT 500. It took Chris Johnson, owner of SCT, and one of the best tuners, Ed Clark, to get this car right. It took from 7:30am to 6:00pm on the dyno to figure this thing out.... all Ed said was that everything on this car is backwards from what he has seen tuning cars over the last 40 years. Ed refused to give up and with support from Chris they got it running.
The point to all this is if you have a 2011 with some deep mods you need to find the best to tune these cars. These 2011 GT500's are not the average car to tune and you need to be prepared for some frustration and a learning curve; along with the occasional wrench light. Also, make sure to reset the computer on any error or I promise it will continue. I also want to say that if you get the chance to use Ed Clark as a tuner you better bleed for the chance... this guy is awesome and refused to give up. Even though I never met him, I would also ascertain that Chris Johnson of SCT has one of the biggest hearts in the car business and really cares about his product and customers; he was on the phone with Ed during his daughters birthday to help me out and stayed with us almost all day!!!
Now the fun stuff. Notice that my AFR is 10.5 thru the pull. The car could have easily made 750+ with a leaner run but it is already scary at 720 RWHP! I am in love with this car and have never been in anything that is close to as fast!
I will post some videos of the run later in the week when I get a chance...
