I got the car back. Unfortunately I wasn't able to get the turbo and stage 4 tune done due to the lead time on the turbo. I will have to get it done once I get back to CA this week. But the stage 3 tune pulls a lot harder than stock, and is very smooth. It pulls a lot harder in the upper powerband. The springs look great and I'm curious to feel how the car tightens up once I get the sway bars installed. It sounds nuts too!
