Dynoing my Grand National
I know I dont have the highest powered car out there but I am happy with what I have and know of every nut and bolt turned on this car. I am still working out a tune as you will see in the first pull, it was fat (AFR in the 10's) so on the second pull we leaned it out a bit (AFR in the 11's) and picked up 20+ lbs of torque! The DynoJet numbers are simply the most common equation of 12% added. This was also told to me by the owner of the shop, its an assumption that I will soon verify at another shop.
