I purchased an SCT XCalibrator 2 tuner from 5 Star Tuning and am very impressed with the new found performance of my V-10. It was great before but now I just love the whole truck. The difference is very notable in both performance as well as economy. Prior to installation of the tuner I measured the stock performance by noting the speed achieved from a stop to a specific driveway. The stock tune allowed me to achieve 110 KM/HR which I did over and over with little to no change on different days. With the new tune that Mike provided me, the truck accelerates to 125 KM/HR over the exact same test area. The truck shifts way better in that from the factory there was a very notable and annoying lag during shifting. I mentioned this to Mike during our dealing and Mike said that he could take care of that as well. I am now very happy with the shifting, they are firm with no lag at all. Above all of this is Mike's commitment to his customer's satisfaction. He is a true pleasure to do business with and a man of his word. I would not hesitate to do further business with him and recommend him to all others interested in a custom tune for their vehicle.

I started looking at what's available online to tune my 02' Ford F-150. I spent a lot of time in different forums asking the same questions. I was in Ford Truck Enthusiasts and was inquiring about a Livewire tuner and I had found out what I wanted to know. I contacted 3 local tuner/speed shops and didn't seem to get any where other than 'I'll get back to you'. They didn't and I'm glad. I got a post from one of the forum members to contact Mike Butler at 5 Star Tuning. I could tell I called the right person. He treated me like I treated my customers when I had a business. I got prompt service with answers to my every question. I initially had an issue with one option but that was taken care of in a prompt and professional manner. I've gotten more interested in tuning my truck as I could tune the carbed engines of yesterday. 15 years of calibrating carbs while working at Holley carb and many years of drag and circle track racing and engine building to apply this knowledge has helped. I'm going to purchase the Pro Racer Package shortly to further enhance the tuning as I am greatly impressed with what the tunes that came with the tuner has done. The tuner covers all that one might encounter during modifications. If it wasn't for Mike Butler giving me his undivided attention for any questions (there's been a lot of emails sent and answered) I wouldn't be this happy with my tuner. Here's a pic of my baby for all to enjoy.

I recently purchased a Xcal3 from Mike with custom tunes and couldn't be happier with the results Mike was able to achieve with my truck!!! I have a 2007 F-150 5.4 V-8, the stock performance was lacking to say the least.
After installing the custom tune, throttle response and takeoff power was greatly improved. I don't have the hesitation when accelerating anymore or at passing. Mike also provided great service, he answered all my questions and was very quick in shipping the tuner. Thanks again Mike for everything!!!
