Once the deed is done, all that's left is to unplug it and turn the car on. As the instructions say, you are now ready to feel the power. After a few days of running the Camaro with his new programming, I asked Dakota what difference, if any, he noticed. Prior to the install, he had noticed a rough idle and a bit of a rough run. Since his install, the engine purrs like a kitten and runs like a scalded dog. To put it another way, there was a noticeable gain in the engine power output.The great thing about this programmer, bedsides the obvious power gain, is if you want to go back and change it back to its stock setting you can. And later on, should you make any improvements to your car, such as bigger wheels and tires or a shift kit, you can go back and readjust the computer's programming to compensate. Oh, we almost forgot to mention, it's legal for use in all 50 states, so if you're worried about smog laws where you live...don't be.
