I just got done putting on fuel pump, fuel filter,iac valve,pcv,plugs,wires,oil change, and the truck feels alittle more responsive but I still feel like I give it gas and the trucks not going how it should, laggy feeling... Anyways stock injectors on truck, do u guys think ill benefit any fron changing them? And do I have to go expensive or is ebay brand ok?

It would be best to get new injectors. But you truly may not feel any difference. Ebay is okay if you truly wanted. Just get a warranty.

Have them flowed. Call around to local shops to see who does it. Shouldn't cost much at all. Probably an hours labor. Pull the injectors yourself and bring 'em in. They basically hook them up to a machine that runs a cleaning fluid through them and matches flow rates for each injector. Then buy rebuild kits for each injector. They consist of new O-rings and pintle caps. NAPA has 'em at about $4 each. It's a fairly easy repair and will save you a ton of $$$.
