I made 347awhp/ 365lb ft
with HKS air filter, o2 housing, TBE, and Mr. Fred's ECU based boost control. 2006 Evo IX on 92 oct. 28psi tapering to 19 at redline. If I could've got my boost to hold better I would've made more power (need to adjust wastegate actuator rod.)

It was tuned on 93 oct. As for the 26 psi: I didn't arbitrarily pick that number. My tuner decided on the boost level. The tune was completely safe (as I saw the AFR and knock counts) and made good power, so I was satisfied.

I do calibration for my regular 8-5 job. It's all in the process. I spent 4 hours street tuning my car and 2.5 hours on the chassis dyno with all of my data analysis macro's previously written.
Boost pressure isn't a limitation, cylinder pressure is. I would run 60 pounds of boost if the turbo could do it...boost is really irrelevant. The amount of cylinder pressure you produce is what counts. I run 28-30psi at peak torque because... it doesn't knock and I'm 3 degrees back of MBT! Perfectly safe as long as you're usign the same grade/quality of fuel.
I would say there's tuning your own personal car...and then there is tuning for someone you don't know. I'm very responsible with my car and when/if it hiccups I have the car pull lots of timing (which lets me know there is something wrong)...I immediately log the issue and correct it. If I were to tune your car and you weren't paying attention or didn't know that the engine missed... you would continue to unknowingly do damage to your car. To prevent this... I would make your car excessively RICH and pull 3 degrees of timing out of my map so that you didn't come back to me complaining that you tried to "clear out the miss" with your right foot and you ended up popping the hg. Then you'd complain to me and everyone else that I'm a shoddy tuner etc. Or...the other side to this "safe tune" is that some hack is copying other people's tunes, cleaning up the AFR's, and making sure it doesn't knock in the 2-3 "tuning pulls" that they do.
Just my opinion on the matter.
