I tried FSWerks at first because Tom had his units on back order. I went with the Xcal3 unit for the svtf and was full of excitement to load the custom tune on my car. With the stock FSWerks 93 oct tune the car ran horrible. It would bog and have zero power. Not a big deal because every car is different. I went through a few different tunes and found one that was pretty decent. I decided to give it a try for a while and see how the car ran.
After I ran the tune for a month or two there was an issue with the hot start. I contacted FSWerks, but really didn't get any where. I offered to datalog and send it to them. I wasn't sure if there was something wrong with the tune or the car. Didn't really get anywhere with that and asked Tom to take a look. He was very kind and offered a test tune. I loaded the tune and the car was like a different animal. Now I'm spending more cash, but at least I'll have a good tune.
