Wow, so I got around to installing the profec today, slowly turned up to 10psi and then 12psi just to see, surprisingly the air fuel ratio is much better now on the higher boost! I'm seeing 11.8 around 6000rpm now on both 10 and 12psi. And that's with the wideband sensor over 3ft away from the turbo, I should be pig rich at redline.

I was planning on only going to 10psi on the stock t25 but I think I will make it 12psi hi boost (the feeling between 10 and 12 is a night and day compared to 7 and 10!) for racing or special runs 10psi for daily driving and if it happens to kill the turbo eventually then so be it I'll goto a t28. Only thing I'm worried about at 12psi is if I'm maxing anything else out besides the turbo? I think I'm still on a stock fuel pump but I need to check, hoping it's a walbro lol.
