ESS 625 Pulley Swap
So I swapped out the standard 96mm pulley with a 92mm pulley to see how much power increase it would yield. Well, basically it didn't do much. It did increase boost by about 1psi...so instead of a measly 5.2psi I'm getting around 6psi. Still much lower boost than everyone else who has this kit but ironically it's make more power than most as well so I'm not complaining. I'll keep the pulley on for the upcoming Shift S3ctor roll-on event but it's coming off since I can't run this pulley with 91 octane.
Just goes to show that the kit is already optimized for the 625 adaptive software.
Here's an overlay of two of my dyno runs today with a dyno I did back in February with the 96mm pulley.
Blue and Red runs were from today's dyno and the green run was back in Feb with the 96mm pulley.
