Low/mid end torque!

Reviewed By James S (CONWAY, AR) Reviewed for a 2013 Chevy Silverado —2/14/2019 4:09 PM

I noticed quite a bit more pull in the low end! I can feel a little more torque. The whistle effect happens under moderate acceleration and boy does she take off then!.

Improved Throttle Response

Reviewed By floyd H (CLARKSVILLE, TN) Reviewed for a 2013 GMC Sierra —6/28/2018 5:58 AM

I installed this at 38,000 miles on my 2013 GMC Sierra 1500 Crew Cab 4x4 with the 5.3 Liter. I can't say the fuel mileage is better in town, seems to be little or no change but on the highway, I am getting approximately 1 to 1.5 MPG more. I can say with 100% certainty that the Throttle response has improved. I can only attribute this to the increase of air flow into the combustion chamber.
