LET, I am at the Texas Mile now. At 3/4 mark 155mph, car falls off again for about 2 seconds. It just kind of shuts off like it is out of fuel. Then it kicks back in and I am running through the mile at 152 exactly like I was running back in March. Call me 832-724-4689 or post up and I will check it. I really need you guys help. I spent a lot of money for the same results and I don't understand what is happening.
