I do need to do that. I can hear it so I know I'm running it pretty hard off the na fpcu. I have a question. My car is an auto & when you boost it pretty hard it will run until it hits redline or fuel cut off before it shifts. You can actually feel it cut back & then it will change gears. Is that normal or is something out of wack? It seems that an auto should shift before then but I don't know.
