i would highly recommend the PPE standard tuner but the best for the buck is the Diablo and for the exhaust i would go with either the Silverline or MBRP exhaust..

I agree...I've done alot of research and asked alot of questions over the past month....and a PPE standard with a 4' Silverline or MRBP exhaust would be good. But if you are towing....you should probably get a Pyrometer to monitor your EGT's.

85-100hp. but just to be safe, its best if you get a tranny kit. you wont regret it. i'd say Suncoast or ATS.

I heard a stock allison shouldn't handle anymore than an extra 80 to 90....if you go over that...I've been told you will Limp it.

That's about what I was looking for.What about the edge products? Any one running summit exaust system? If I Delete the cat will it set codes? Sorry for all the questions.

Alot of people say the EDGE stuff is hard to beat with all the digital monitors...but I've heard nothing but bad things about them actually working and lasting long. If you want what they call good "Bang for your buck" get the Diablo sport predator...if you want a good all around product get the PPE. And some people say that if you delete the cat it will and some say it won't...I basically think it depends on your truck. I decided not too because I don't want to take any chances with codes...but then again I'm a wuss. Plus I had a couple diesel mechanics tell me that a Turbo back system really doesn't do much to a duramax engine...but that's their opinion.
