7875 + 5.9 + E85 + Megasquirt

This was surprising to me. My gt45 spooled much easier/quicker. I wonder if it’s our downpipe size? Which exhaust housing are you running on your 7875?

The packaging is much nicer on the 7875, and success stories pretty universal across the web.

The car sounds great!

Could be that the GT45 spools faster. I don't have any old logs from when I had mine. The 7875 just feels like it spools faster based on the seat-of-the-pants meter. I don't have any logs of me smashing the gas pedal since that's usually a waste of tires on the street but it does go into positive boost around 4k rpm when I ease into the throttle. The converter stalls to 3500.
