just wanted some input from you guys. Ive got a 2000 chevy ext short 4x4 that im going to be moddin my question is does true dual exhaust make alot more power than a catback system? and how much power can you expect from a nelson tune over a super chip? thanks
True dual isnt going to add much more then a catback... And Nelson is just better all around... not just in hp gains.

Honestly for the money I would definitely go nelson on the tune. As far as duals I didn't notice a whole lot more difference in my truck except that I was running a better muffler. It does offer more flow but in the 5.3 that's not that big of deal. You will notice more difference with a nelson tune over anything.

Sticky/broken gauges? I can help. PM me for details.
Go with Nelson over any reprogrammer. They do a great job and are really helpful if you need to make changes. I have an 05 z-71 with the 5.3. The tune they did was very effective. I just decided to sell my truck and they gladly returned everything back to stock. The most cost effective thing you can do is a cam swap, aside from forced induction. I have a Vinci High Performance #112 Crane cam that I used for 4 months if you're interested. Good luck, contact Nelson either way.
you dont need super open exhaust like true duals unless you are planning some serious power IMO. If you are leaving the cats its not going to be that much more flow anyway. A good 3" catback is more than most will need IMO. and the Nelson tune is leaps better than any hand held can do.

The best advice I have ever heard:... Only take B( . Y . )ST advice from someone that is CURRENTLY running a turbo setup close to, or bigger than what you want......
welcome. What are your goals? Start with bolt ons, gears, stall, cam, and tune.... Maybe even N20 or FI after that...

I don't have big plans for this truck since its an extended cab 4wd. just a cat back and a tune but i would like to get my hands on a 2wd single cab then i would go all out
Agreed, No need for duals, get yourself a Nelson tune and start there.
