Went to the track last night after installing the tow flows. Truck made a pass of 7.85 @ 88 in the 1/8 vs a previous best on street tires of 7.92 @ 88. Drive pressure dropped to 48 psi vs 54 previous with the same boost of 38 lbs. Egts dropped about 100 degrees at the track with a lot better recovery rate. Thanks Rick and hopefully I will get some numbers on the dyno and with the drag radials very soon.:thumb:
