Hi D, It took me a few times to get mine right too. Dave gave me a larger W/M injector for one side. Overnite Shawn you card, with your dyno sheets..explain whats happening he will send you a few different cards with some different timing/fuel programs, change the injector, and you will be running great...keep the 96 PCM, that has nothing to do with your problem. He sent me 3 cards and the first one did the trick...Keep the card you have now for your race fuel program...NO MORE PINGING...AL...
