I can't wait to see your logs. I'm curious to see what your AFRs, timing and fuel rail pressure look like. From everything I've read and discussed with other tuners, the stock fuel pumps just can't keep up with the amount of air mass flowing at 20-22PSI, leaning out the mixture. Also, I believe pushing the stock turbo to that level may be putting a lot of strain on the compressor. I'd love to see the compressor maps for the stock snail.

With fuel-it port injection and an Active-8, we’ve made about 530hp. Another problem at these power levels is excess heat. "

So while I don't know if I will ever change out the turbo, I feel I am well within reasonable parameters with sensible supporting upgrades like the TMAP and the diverter + that literally just arrived.
