Thanks for the link and info. I went ahead and bought the Stratified tune...just waiting for them to build and email it to me.
In the meantime:
I imported my Cobb AP datalogs and compared stock boost and air fuel ratio vs the Cobb 93 oct stage 1 tune. What is interesting is that it appears that the stock tune was holding spool up back to keep it gradual. But then the Cobb tune doesn't boost as high but it boosts earlier and stays flatter longer before tapering off more gradually and then holds higher boost to redline. AFRs are mostly richer for the Cobb tune which is interesting...
These were 3rd pulls from earlier today.
