What should I do with my Silverado 4.8?

I just purchased a 2011 Silverado with a 4.8 and am looking for ideas to increase power and maybe fuel economy. Already have exhaust. I’ve heard different opinions on a new intake vs just buying a new filter???

Which is better Chevy Silverado 4.8 or 5.3?

Most truck rags have noted that the rear wheel HP of the 4.8/5.3 is down compared to what Chevy has claimed. The 5.3 is weaker than the new Triton 5.4 as an example. I suppose that it’s all in waht you’re expecting. My 4.8L 5 spd has enough power even when loaded to the max GVWR. On some steep grades (6% or more) I may have to downshift.

What kind of power loss does a Silverado have?

Silverado with a 5.3 v8 and I have had a terrible power loss problem. From a dead stop when I step on the gas its really boggy and wont pick up speed until about 3000 rpm.

What kind of engine does a Chevy Silverado have?

The Vortec 4.8, 5.3, and 6.0 liter engines have a main accessory drive belt for the water pump, power steering, and alternator. The main belt has a GM auto-tensioner (which maintains spring pressure to automatically adjust for optimum tension as the belt wears) and an idler pulley.

What’s the problem with my Silverado 4.3 V6?

2007 Silverado 4.3 V6 -39,000 miles…no engine or tranny mods. No exhaust. I do have a K&N air filter that I just cleaned. I don’t think I have that MAF sensor on my intake like the more expensive trucks do. My problem seems to be a lack of power, like it just doesn’t want to go (V6 jokes aside).
