I was gonna get the tune but can't fix my speedo so I just don't see it worth it. the speedo fix is what I wanted the most out of the tune. I have a 04.
Why can't you fix the speedo on pre-2006 models?

The 02-05 P10 PCMs are finicky to say the least, speedo correction via HPTuners or EFILive is hit or miss in my opinion. More likely a miss...Call GM and complain they used a b@$tard PCM on the 02-05 trucks (only GMT360/370/305 vehicles and only the 4.2L engine) that cant be adjusted properly. Even tuning the VE tables is more complicated than a regular LS1 PCM or an E38/E67 (Camaro, Fullsize, TBSS, etc).

I can deal with finicky, If they need a truck to use to get it right I could hang out for a day in Mooresville if they give me the tune for dirt cheap or free. I live about 2hrs away.

I'd also like to know if there is a cohesive rundown on what is altered and the options available for the 02-05 trucks.
I hear so many good things about this, and definitely want to go with it, I'd just like some exact specifics on what is changed.

Doubtful, PCM4Less bought an 05 I6 to develop their 02-05 I6 tune with and got it perfected (except for this tire issue) so they sold it.
Its to the point that its not worth their time to hassle with it, and I dont blame them. Im messing with it today and again next week on my 02 I6 simply because my brother's driving it and its bugging me that the speedo's off. If I was driving it, I probably wouldnt worry about it and just use my phone for gps.
Doubt I will ever get the tune then, It's not worth it without the speedo fix. Primary reason I would want it.

I permanently mounted my GPS directly in front of the speedometer. It takes care of the problems with the incorrect speed.
I love my tune and recommend it to everyone. I want to get my wife's Bravada tuned, unfortunately I am down the drive thru money in my wallet after buying Christmas presents for the kids.

BUMP
On the way home from my Sister-in-law's on Christmas eve my daughter -- who is driving the Envoy while she's home from college -- was complaining about its lack of acceleration. So that does it, its going to get a tune.
Looks like GM used different PCSs in different locations. I want to make sure I'm looking at the right thing under the hood (2005 Envoy). Is the PCM at the top left of the engine near the alternator with three connectors/cables on it?
What should I request as options? Leaning to shift level 2 and deleting the torque management but there is always a chance I'll tow my trailer with it again, 4500 lbs. Otherwise the Envoy is stock including the tires/rims.

Yes, that's it. As far as recommendations, you might want to talk to the folks at PCMforLess, and tell them what you plan to do with your truck, then they can advise you what could be a good fit.

If you have stock tires, 29.5", the speedometer will read properly. If you had a 2006 or newer TV the speedometer can be adjusted in the PCM.
