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.

Gms3 may not be as good as a custom setup with hp tune but it doesnt suck. I think most dont use it because the ac doesnt work without modifications. I thought the zzps3 had all the features of the gm but the ac works?

GM Stage 3 is around 650 which is cheaper than zzp stage 3 by the time you add everything you need. Can you use HPtuners on GM's PCM? Also from what ive seen, they put down the same power as zzp stage 3... both around 250whp

Ah I see, if this is the case then it totally makes sense. Right now I do have full bolt-ons and I was considering cams and valve springs in the future. Might be a dumb question but would that require an additional tune, adding cams and valve springs?

Such a typical ignorant statement.
You will need springs when you swap to performance cams.
ZZP stage kits do not have any of the features of the GMR S3 PCM. Features like adjustable rev limiter, high octane mode, and calibration for a 50 shot.

If anyone wants to see what an M62 car can make with GMR S3, look up the user micro.
His car made 260 whp, full bolt ons, 93 octane.
GMR S3 responds very well to breathing mods, ie. exhaust, ported head, cams, etc.
It was tested and refined on time attack.
I spoke many times with the engineer (Bill Duncan) who worked on the calibration, and built my setup with help from him.
I wouldnt have if I didnt get the ok from Bill Duncan, and in the end my setup works great.
All parameters are in check, fuel trims, a/f ratio, kr, injector pw's, etc. No lean spikes & a/f holds throughout the pull.
I dont go on here on the weekends.

No, not how it comes as a canned tune. Although, you can have ZZP tweak it how you want.
GMR S3 commands an 11.3 afr, 22-23 degrees timing advance with 93 octane, 25-26 with race gas.
The ZZP tunes do not run that kind of timing, also because they come with much smaller pulley options.
The features of the GMR S3 PCM are wonderful as well. I can adjust my limiter from 6.5k to 8k anytime I want. High Octane Mode is a blast, and the 50 shot calibration is a bonus.
w/o hp tuners, you will not be able to have that kind of flexibilty with a zzp stage kit tune.
