What performance mod should i do next with my lm7 5.3 i currently have a 216/220 5.60 lift cam with a ls6 style typhoon intake, k&N intake, cat delete, catback exhaust eletric fan 3.73s it made 280 hp and 280 lbs on its best run what will be a good combination with my setup i was thinking headers but i will have a hard time fitting some in my Colorado and might not be worth the trouble or the cost so maybe heads or stall?? Let me know thanks!!!!!

 

Headers.

Your hoe is sucking air, but not pushing it out.
Dump that ls6 intake in favor on a 08+ truck intake.

And you have a shitty tuner<------

 

Yeah, truck intake will make more torque for sure.

 

 

Is the truck intake really better??? And yeah the tuner didn't really add much horsepower but he gained a lot of low in torque will the truck intake add more hp and will it need a retune
