+1 which engine,what year, do u have stock fuel pump,etc. but even if everything stock, pump etc. should b fine, just let ur tuner know all ur specs

My bad.. well the shop where I get my tune from said that if I do the cam swap.. then I will need better injectors...I've seen a lot of other cam swap threads tht don't say anything about changing injectors.. so I got confused :/

What mods and such. Give us a run down so we can help. A cam only no need but depending on what bolt ons and such things can change

2004 Silverado 5.3.. k&n intake, pacesetter longtubes and 3" y pipe , magnaflow 2.5" 1 in 2 out,efans,vette servo and tune. Thanks guys

I would say ur fine that's a pretty mild cam and good bolt ons don't think any need for bigger injectors. One way to find out is cam it. Then scan it to check ur injector values

Ok .. how will my truck run without a tune for the cam? I kno I won't get the full benefit till I get the retune but I'm asking because Im doin the swap with some buddies and it mite be a day or 2 at most till it sees my tuner

It won't want to idle very well on its own, and you'll be two footing it at every light, but it should run well enough to get you around for a day or two. Just don't try to lay into it at all before you get the tune.
