Take a close look at those torque numbers all the way down to 3,300 RPM. Picked up over 20 lb-ft there, picked up 11 lb-ft at peak with a lower peak RPM and carried the gains all the way past peak HP. Look at the area gained under the curve and that's pretty significant, it basically flattened out and raised the entire torque curve by an average of about 15 lb-ft. Definitely worth it IMO. With a drivetrain combo that makes use of the engine from 2,500-5,500+ RPM that's a big gain in overall acceleration.
