Something is not right with the new graph because the numbers listed in the average column state an average
torque gain of 20ft/lbs across the rpm range? That's substantially higher than the average numbers listed on the first graph yet the peak HP numbers seem to still be close to the originals?!? Torque gain only hits 20+ briefly at around 4600rpm so there is now way the average could be 20ft/lbs.
Also, I was always under the impression that the "peak" number was the largest gain at any one point in the powerband, but they seem to label the actual peak in the graph itself as the "peak" gain. Am I out to lunch here?
I'm sure aFe will have an explination but it looks a lot like number massaging IMO.
