Can you help me identify this chip. It is the one that is in the car right now. I'm getting horrible gas mileage and I want to make sure this isn't a strip chip. I drive on the highway most all the time and drive it gently. I'll accelerate sometimes and all the sudden the gas guage drops like 1/8 of a tank What the heck is wrong...I think the 69 Pontiac 350 I sold with a 600 cfm carb got better mileage than this!
