I blocked the main intake, and tried just running the 1 3/8" manifold heat tube. temp outside 85 degrees. car stumbled anything over 1500 rpm. unplugged the main intake tube, now running both tubes full time . car runs fine. got 56 mpg in 310 miles. 150 of those miles on freeway at 65- 70 mph. passenger window open.wife needed air.
