This may seem kind of silly but I'll be taking my car back to get the chip re-burned. I have an Autologic flip chip with 2 banks and will be burning one program with pump gas and another with 110 octane. I was planning on doing the pulls with race gas second, but what's a good way to empty the tank, at least as much as possible? I was going to run it down extremely low with the 93, almost to the point of running out and then add about 6 gallons of 110. I just don't want to be in the middle of a pull with the boost at 10 pounds and run out of fuel. Any ideas?
