That is crazy that I am on a bigger pulley then you and my injectors are working harder
.
I am on the GM stg 2 version. Only mods to the tune are codes shut off and boost reduction in first.
What are the odds of you pulling the GMR file from your PCM and sending it to me?

The difference between the S2 pulley & S3 pulley is minimal at best.
S2 runs super rich. Cmnds a 10.8 AFR or so. GMR S3 cmnds around 11.3-11.4 AFR. Makes some extra head room for the injectors. Lean your tune out a tad.

Yep, I was so relieved when she fired up first shot. No issues at all.
Coolant bled perfectly to. Nice warm heat, and perfect engine coolant temps.
I will post videos of the car soon. I took some cell phone vids in my garage, and the echo made the videos sound like crap.

I cracked the limiter when I first punched her on Saturday. I wasn't ready for how quickly she revs, haha.
The stock lsj exhaust ports are really pathetic when you compare them to a properly ported head.

Not really. The 10 or so extra hp I may gain isn't super important to me. The car runs mint with all the mods I have and has never failed me. I'm not changing that.
