Whats the practical boost limit for the stock turbo? I think stock it maxes at 20PSI, but with a boost controller whats the highest you should go for everyday use? I was thinking something in the 25-27 range, correct me if I'm wrong.
40 psi. max
The LLY and LBZ chargers can take a bit more boost than the LB7. I still like it around 30 with maybe spiking to 31-32psi max on the LBZ.shit mine hits 31 all tha time and i have never had any problems....and my buddies have the ppe boost builder thing and hits 36 and he has had no problems...i guess it just depends on everything i dunno..
LMM's can reach really high boost with tuners. I have to actually lower the factory boost tables with EFI to stay around 30psi when adding fuel. Might want to get a gauge on it.GM says that 20psi is max on the LMM. I currently am running PPE's level 3 tune and don't have a boost or pyrometer yet, how much more boost do you guys think I might be seeing over stock?

I take it you have the edge stacked with the PPE, since the Edge alone won't command that much boost.my edge would read like 32-34 just depends and during the 4-5 shift it would spkie to 36 is that an accuraute reading or no.
