Looking for a inexpensive tuner for my 2014 Silverado 5.3. I have a borla atak exhaust and K&n Blackhawk cold air intake. Its lifted 6 inches with 35s and the speedometer is off by about 5 miles an hour. I'm not looking for a high performance tuner just something to play with and fix my speedometer and mostly get a little better mpgs. Any recommendations?
