Who is useing Header extensions?

Well I got to take my dakota to the track today
I just had back surgery a week ago, so I had to have my friend race it for me. He was a green horn at first
Fastest thing he has raced before was his 15 second mustang. Lol the Temps were in the low 70 today his fastes pass was a
1.57 60 foot
1/8 7.16
Mph 95.63
1/4 11.27
Mph 114.86

The last time I raced it the temp was 50 degrees and my best pass was
1.56 60 foot
1/8 7.15
MPH 95.98
1/4 11.24
Mph 114.90

His last pass of the day the temp dropped from the mid 70 to low 60. He blew the tires off and ran a 11.34 at 115. To me I dont think the torque tubes changed a hole lot
Maybe gave it a little more low end. I still think this truck has a lot more in it. Just needs a lot more tuning. Biggest thing is I think the converter is not right for my engine set up. My friend was shifting it at 6500 and he said he was turning 7500 at the 1/4 mile finish line. Which I dont think is right but thats what he said he saw. After I heal up from getting my back worked on
I am going to pull the converter out and get it sent in for my set up
Come on spring time. Lol.

laying down in the backend a good bit.
Mph is low for the ET, and quite low considering the MPH at the 1/8th
