Sounds about right. If you are going on a road trip and want to run 87 just change out the 3 bar back to stock and re flash it. only takes about 5 minutes and the plugs can stay. now you will have almost a 100 WHP and over 100 WTQ you will find the car can now spin the tires so with this comes wheel hop. One more thing you will need since we are spending your money is the AD trans mounts, they come with 2 mounts that are stiffer then stock. I suggest only putting in one as they pass vibration to the body. At first it's a bit loud but give them a few thousand miles to mellow out. one is more then plenty to keep the wheels planted. ENJOY!
