So many gauges built into this device I don't know which ones to use.

After installing the chip I noticed a drop in power at the lower RPMs. It takes longer to feel the engines power. At the same time I have noticed a big increase in power and accelleration when Im in 4 wheel drive. It hauls ass in 4high now. I have noticed a 1-2 mile per gallon increase.

Programmer had to be updated but otherwise easy to install. I've noticed some slight pinging at part throttle and engine knock at full throttle. I am going to contact Hypertech and see what they say about that. Fuel economy is better but may need to run premium fuel. If you are considering this product carefully read there web site about model specific features. For example unless it mentions shift firmness or adjustable shift points you are going to have the stock settings for an A/T.
