It got warm enough here today to take my 2001 LT out for the first ride with the Gemi chip. It’s fantastic how the fueling is absolutely flawless! She’s never run this well! All the way from idle to 7K is smooth and quick. Anybody contemplating this mod should do it. Im not going to be able to check fuel economy for a while. I did the speedo mod also, it’s within 1 mph of gps reading right up to 100 mph! Now it’s snowing.
