Excellent warrantied mod
I went with the Ford Racing tuner for warranty reasons. I know its gains aren't claimed to be as great as other aftermarket tunes but between the warranty and the security of knowing it came from Ford Racing, I had no problem moving in this direction. I installed the KandN air filter before the tune since I had to register the ProCal online and wait another business day for it to arrive. An interesting observation was that even with just the filter, I noticed a very slight increase in throttle response and a slightly louder intake growl, which makes sense since it flows better than the stock filter and has less material to dampen intake sound.
I had the ProCal installed at my local Ford dealer, which is required for the warranty. I was charged $70 for the install, which took about 40 minutes. I drove fairly conservatively for the first 30-50 miles or so, figuring the computer might need time to adjust. After that, the improvements have been very noticeable. First, you notice the throttle response. The throttle feels excellent and the slight mushiness of the stock calibration is gone. Getting off the line in first gear (6 speed manual) is surprisingly smoother, as is the shift in to second. These were unexpected but welcome improvements. Perhaps the most significant difference is the low and midrange punch. This tune raises torque by 60 lbft at 1500 rpm, and when out on the road it is very easy to feel the extra torque. Its not like adding a supercharger, obviously, but for a simple tune I was very pleased. Raising the rev limiter from 6900 to 7200 rpm has helped prevent me from hitting the limiter in lower gears, and the top end pulls a little harder, although the difference isn't as great as the low and mid-range improvements. Also, as a previous review noted, the car engine brakes more strongly, for what thats worth. Now I am very sensitive to the details and sensations of my car and driving, so I may notice the differences more than other drivers might. I don't want people to read my review and expect crazy, massive gains, but considering this is a reliable, safe tune, I am very pleased with the results. I would recommend this to anyone looking for warranteed performance. Oh, and I have not had any pinging or ticking as a few earlier reviewers had experienced.
