I remember this build. It is so amazing! I wish I understood tuning and what it would take to tune a turbo build. I think turbo is the beat of both worlds, good gas mileage and power when you want it. What fuel do you need to run with moderate boost? Where have you found you have the boost limit at (the limit programs controlled by the key switch). Thanks for reposting, I read through it all again, it's a great thread/build. Amazing work.
