yea a good performance exhaust, and an intake should do the trick! i dont know if they make programmers for them or how well they do compared to diesels, but you can look into that. im not sure if the rewards out-weigh the initial cost of the programmer as it does with diesels by giving better gas mileage

 

Sorry I didn't get back to y'all. I decided that ill see what I can do about the price; before I do, I forgot to add, that when I started it up @ the dealership, it sounded great exept for a slight whining noise, could anyonetell me what that may be. And thanks for all of the replies!! Keep em comin!

 

not sure what the noise is, but my buddy has a 1998 2 door tahoe with the 5.7 in it. makes the same whining noise that your talking about. might just be how they were?

or maybe theres a common problem with a vacuum or air leak of some sort. who knows

if you do figure out the whining noise let me know, ill check out my friends tahoe and fix his also

 

Hi! Thanks for getting back so soon! I did some research elsewhere and I THINK it is just how they run. If enyone else knows anything about this go ahead and tell me anyway. Thanks. Once again keep all of those otthe replies comin!!!

 

Hello people??? I still need more advice and opinions!?!?!
Keep m comin!

 

id post in a different section. might get more replies that way

 

Gulp gulp gulp gulp gulp gulp gulp gulp gulp BUUUURRRP! Thats the sound of the gas tank while youre filling up, pulling your trailer, with that rig. The 5.7 is a good engine, but it can get thirsty when pulling a load. Hill climbing will be an adventure and quite an eye opener. you may also want to look into airbags to help your rear suspension, and keep things level. Just a thought.

 

350's do like to drink gas
