Performance upgrades for 2011 Silverado

[cantdivefiftyfive]

I'm trying to find some upgrades I can do to my truck to get more out of it. I've already done a cold air intake, maf upgrade, a throttle body spacer, a programmer, and cat back. Any suggestions would be great.

Long tube headers, ignore the cats. LSx engines love to breath and the headers will open up the door for big gains down the road. Plus some sick ass exhaust noise.

 

With a sawzall and jack stands, you can easily do the exhaust in a day.

I thought that shortys gave better low end torque. I've seen some that will bolt up to the stock exhaust, but I wasn't sure if it would be worth it...like if it would actually gain that much from it.

I'll dig up my dyno charts, but my 6.2L made 30 hp at the tires with just the headers, no tune.

Very nice indeed

Better upgrade your tranny, rear end, and all the other driveline components lol. Those motors are pretty strong and have been known to hold up to turbos and super chargers but most everything after the motor is going to be weak points in the system if you start increasing the performance too much.

The LS motors like there boost... I'd look into an HD kit for the trans though. Cheap upgrade... Plus get the tranny and motor tuned at the same time... Save yourself repair costs in the long run

You will still get some hp gain using shorty headers. JBA and edelbrock are some good brands.

By "programmer" do you mean just canned tuned? If so, a "custom" tune will help you get the most out of your upgrades. I wouldn't get the tune until you are finished adding your bolt-on's.
