I have a 06 Silverado with a 5.3l 3.42 gears, looking to make more power but this is also my tow pig, usually has a 18ft car hauler with two rzrs. Looking for advice on what power adders to do wile still keeping my towing ability.

 

Change your gears first thing!

 

Gears for sure if you want it to tow better. 3.90's or 4.10's would be better than those 3.42's. You might lose a tad bit of fuel economy though.

For easy upgrades to gain power you can add a intake tube and some headers, then get a really good tune to help pick up some horsepower.

Past that you will be into a camshaft upgrade or more. Take into account that the more power you add the worse it's going to be on the stock transmission. And with you wanting to tow a big trailer, that is going to take it's toll on the transmission aswell.

 

Yea I planned on intake tube and headers, I already installed the 40k trans cooler, I had a regular cab 05 that had 4-10 gears, would a small super charger be good like a p1sc or tvs1900 for towing?

 

gears, headers, tune.

TVS1900 would be great for towing but its $$

 

This^
Headers, cold air intake, exhaust, tune all increased my gas mileage. Then throw in a set of gears which will help very well with towing and make the truck more fun. it should balance out that you get good fuel economy, have more power,and it's a lot more responsive from stoplight
