15 Silverado 6.2, Tune, Flex, Maggie, Kooks headers
Here is a 15 Silverado with a TVS1900 w/2.9" pulley and full exhaust. As you can see on the dyno chart it puts down over 500whp on both 91 octane and E85. However it makes nearly 40 more ft/lbs of torque on E85 and makes over 500 ft/lbs from 2500-5000 rpm. It makes great usable hp and torque!
