4.7L Auto, CAI & HF Muf. Wanted more power (&/or) MPG & adjust speedo for big tires. I can't give it 5*'s because I can't honestly say it was worth 300 bucks. There are other options that do these things for less. If you have a newer truck, you can probably get more bang for your buck using more than 4 tunes. I noticed power gain in 91 performance, but only got 14mpg. Enough to notice driving, but gas is $.50 more. Gain of 1mpg (16 to 17) in Fuel Saver Mode on 87. Not much savings there either.
