Polk Performance

Stepped outside of the normal dyno day today. Bob Bills decided it was time to dial in the his modified.

Tune of the morning, daily driver tune. Adjusted shift strategies , turned of DOD and ran it through the full dyno tune. These trucks make some good gains in the lower end where you spend most of your time driving. The dyno curve starts about 2000 rpm, but you can see the large torque increase below 2000 rpm. It still made good gains through out the power band.
