Why don't more people go GM Stage 3?

Just curious as to why people don't go GM stage 3 over other stage kits. I know each have their benefits but the PCM GM offers with all the options seems to be pretty unique. Also, if someone is buying ZZP's stage kit and getting a 2.9 pulley, why not get GM stage 3? Just curious to hear people's reasons. I kinda wanna go GM stage 3 just to be different and eventually utilize the 50 shot of nitrous feature.

2.9 is best for my application. I can beat it longer without heat build up and not break trannies. I don't want to be carful and have to baby my rig. I want to beat the ***** off of it. With a 2.9 and stock rev limit I can't hurt it when the tires leave the ground and I can stay stupid. Rpms will spike over a thousand rpm higher than the rev limit if you are spinning or your tires leave the ground so build it mild and hammer the hell out of it.

It is still GMRS3, if the a/c unlocked is the only thing altered. The a/c control, is a simple on/off deep within the calibration cells. Vince figured out the code and switched it back on.
There is no change to the actual calibration. All tune parameters are as they came from GM.
Trifecta S3 is when you have Vince tune you via Trifecta, but you get to keep all the neat features from the GMRS3 PCM. Which looks like what 06blackbalt may have.
This was a great feature, because you were able to utilize the adjustable rev limit, high octane mode, and nitrous algorithm, but could tune for the use of larger injectors, smaller pulley, or any combination of the two.
My IDC's are no where near 140% which is why I can still rev her out and take advantage of the cam peak at 7100 rpm and ported head benefits.
Did you get other tuning done other than your injector tables for the 60's?
Igniton on, around 50% throttle starts to move the limiter in 250 rpm increments.
The further you push down, the higher the rpms. It's touchy to.

To make a general clarification, because no one understands the difference still....

Time Attack made a bit more power than me off nitrous with 42's. They can take a beating.

You have Trifecta S3. Still based off the GMRS3 calibration so nothing wrong with that at all.

Here is Micros graph next to my graph. His car has similar mods to my car minus the H62, ported head, & cams, and is a good example of what a fully bolted GMR S3 car w/ M62 can do.

So not a huge difference, but it's good for a 1/2 lb more boost and quicker windup of the blower.
Even for such a small difference, it was a noticeable change going from the GMS2 pulley to GMRS3 pulley when I was only GMS2 back in the day.
Also, dont get too caught up on peak torque numbers, because the torque curve is very flat with the GMRS3 tune, and carries it well.

Staged I like how much flatter and broader you trq curve, well not even curve LOL, is with the stg1 cams.
People get to hung up on peak numbers alone. Pat attention to the graph.
M62 stock cams: 3000=210 trq, peaks at roughly 4700=238 and falls at 6500=under 210 and keeps falling hard. HP is already peaked and dropping off
H62 stg1 cams: 3000=210 trq, peeks @ 5000=242 and then keeps trq higher then 210 all the way till redline. Hp doesn't even drop off and keeps building.
Picking the right parts to keep things efficient works out here.
I've ran the Tirfecta GMstg3 tune and loved it. Being able to adjust my own rev limit and having the HOM was awesome. It's having several tune in one and being able to change things on the fly without having to use a laptop

You are correct there is a lot more to a strong running car than peak numbers.
