Ebay GT45 + 5.9 Magnum + E85 blow thru

:popcorn: subscribed ! Are you going to dyno it?
Not at the moment. If there was somebody around here with experience tuning the Fitech with Turbo and E85, maybe. But I figure it's producing about 425hp at the flywheel based on my ET/MPH and weight (3200lbs). I think the full exhaust is really choking it. I'll uncap the dumps next time and try increasing the boost a little. I also have some exhaust leaks in the hotside I need to get squared away that are annoying and could be affecting AFR readings.
