I don't think I'll be going back to Govt. MotorsI can't help you with the stereo issue.The noise you hear under hard accel, is pinging. You have 2 choices, retard the timing a degree or 2 or run a higher grade of gas.Stock timing is 10*btdc but most people can advance up to 14* if they run 91 octane for the free HP. I'm running 12* and still able to run 87 octane.If you choose to back the timing off, read your Haynes manual. You'll need to pull something called a "spout connector" before moving the distributor. The spout is located near the air filter and takes the computer advance out while setting timing.good luck</blockquote>
