I'm trying to go single plane on the DD 408 M6. I'm looking to pick up power from 3500 to 7500 an the intake is really limiting my motor's potential up top pretty bad. It doenn't like to pull hard anything under 3200 an won't pull much harder around 4300....
almost flat line with not much climing. The car made 527/475 on motor stock L76 intake, TSP 92mm TB, 1-7/8's LT's, True Duals, 4:10's, 65lbz., 255 pump.
