Performance Chips Reviews

After reading the many good and mixed reviews I did not expect too much when I bought the chip. WRONG! The improvements are huge! As a hobby racetrack man I admit to drive my Jeep Cherokee Sport hard and very fast. (Upgraded Billstein and airbox). I also rev up the engine hard and use the automatic gear shift to shift manually. So, installation took 2 minutes, the engine now drives much easier, less effort, - or same effort but 15 miles faster on the freeway. what was 75 is now 90 easily. also fuel consumption is lower - or I should say the same as i push harder. So I get same mileage with more power. Have not tried normal driving style yet. It revs up faster, more at ease, it feels like a more supple engine. In all I am very satisfied.

I am extremely happy with this purchase. Installation was easy and the amount of information that it can display is great. I have a 2002 Ford and had to contact support to get a beta update for the unit so that it had all of the PIDs available. The support staff were a pleasure to work with. I believe the production version of the update will be released any time now.I would highly recommend this product.

Great System Easy to Install I have already notice mpg improvement

I really like this tuner. I can't say I noticed much power gains, but I primarily got it to adjust the transmission shift points and firmness, and it does that very well. My truck shifts much smoother and is more responsive. The install was easy and programming is simple. Some say it is too small, but after the newness (wanting to stare at it all the time) wears off I think the size is perfect. It doesn't take up too much space and is still readable at a glance. I have a friend who spent a lot more to get the Edge Evolution CTS, which does have a much better looking display, but fewer displayable stats, and it is way too big. The Bully Dog gets the job done and the price is very reasonable. I would buy it again if I had to.

The info on the website was a little misleading. For my Tundra and other Toyotas this is an in-line device that needs to be installed behind the speedometer cluster. Don't let that discourage your interest, the instructions were very well written and it was actually quite easy. Patience is important so you do not break any of the small clips. The programming portion took seconds once plugged into the computer, the software is very easy to use. So far, the device has done exactly what I needed it to do, adjust for larger tires. I double checked the calculations myself and everything is right on. Also, I have seen an increase in gas mileage of about 1 mpg, a nice bonus.
