sniper tuning

Anyone ever hear of sniper tuning?

I was at a shop and the mechanic told me that he could tune my car by using sniper tuning software to adjust my factory computer settings. He said it would save gas and increase horsepower. Was wondering if this is even possible.

>>> The Sniper Tuning Suite is great for both Shops and Racers.  Sniper has taken a different approach to tuning, making it much easier for the common enthusiast to pick up the software and generate a custom tune easily.  Its priced a bit cheaper than other tuning software, but gives you access to everything you need to properly tune a vehicle.  Haven’t had any issues with it at all!
