Here is the dyno of how the car left the shop. The more I drive it the more I love this freaking turbo. Its really a challenge to stay out of boost and as a result I need to change my driving style if I want to get anything over 16mpg. It's almost like the turbo spools on the freeway with just the weight of my foot on the gas pedal.
If an 18G and a 35R had a baby, that baby would be the EFR 7670. I took it up in the mountains the other day even though it was cold, wet, and I couldn't really get on it I would say this thing is every bit as responsive as my old Greddy 18G with about 100 more whp and I'm still only at 15 psi.
Note: Disregard the analog 2 channel on that graph, his boost pickup was having issues.
