More so, and most annoyingly, the car has this horrible habit of hesitating when I hit the gas pedal whether it is from a full stop or low speeds. It seems like it takes the car a minute to realize that I want to go faster, regardless of Drive, Drive Sport, or Manual Shift. I tried looking around online and I read that there is a possible timing issue that is corrected by a software update? Mind if I leave it here?"
The SA wrote everything down including my "quick research". He did say that it was very unlikely that it was a software issue because when you check your car in they get a sheet that prints out of any outstanding recalls on the car. Then I get a call saying that not only did they verify those problems but that my DME was throwing 9 different errors. The update fixed it all. Found this odd because for anyone who knows the car was in and out of the dealer for what they suspected was an engine problem just over a month ago, and you're telling me they didn't see any of the DME error when they were checking all the electronics and such then?
Anyways, car is back now and he is happy. Got the cobb aggressive tune back on him and going to install the AA FMIC this weekend.

Glad you got everything going!

I've only seen percentages but no indication as to which car...and one graph that had numbers but they were really low and I noticed the graph was for a 135.

We generally only show percentages as it should be relatively accurate regardless of dyno and car. We have a Mustang dyno in-house, so our numbers are usually a bit lower than a DynoJet. What you're really looking for is gain from your stock numbers... percentages are the best way we've found to set expectations without having dynos come into play.
