Off-the-shelf maps are fine for a stock car on good gas. The second you add a downpipe, a turbo, or ethanol, you want someone reading the logs. That's what we do: build the map, drive the car, read the data, revise, repeat until the numbers and the butt-dyno agree.
MHD and Bootmod3 across N54, N55, B58, S55, S58. DME unlocks and bench flashing for the newer cars, done in-house.
A map for your exact hardware and fuel, the logs we tuned it on, and a shop that'll keep revising it when you change something.
Stage 1 is a tune on stock parts. Stage 2 is downpipe plus tune. Past that it's a build, not a stage, and we'll scope it with you.
A tune doesn't fix a boost leak or a weak pump. If the car isn't healthy we'll tell you before we flash anything.
We'll ask the annoying questions, then give you a real number.
