Velos Designwerks BMW F10 550i N63 Twin Turbo V8 dyno tune results - 441 whp and catless CEL (check engine light) disabled
Velos Designwerks recently did a custom tune for BimmerBoost member Jimefam's F10 BMW 550i. This user was having trouble finding a tuner who was able to tune his car around his mods and disable the check engine light he had as a result of his catless AR Design N63 downpipes
. For a while now Dinan seemed to be the main option for these motors
but they were not willing to do custom tunes.
Velos was able to not only turn off the CEL (check engine light) but also was able to gain considerable power. 441 wheel horsepower to be exact with the downpipes which exceeds the Dinan Stage 3 which put down 411 to the wheels
on a dynojet considerably as well as the 386 wheel horsepower baseline. We have not seen a higher horsepower N63 dyno graph.
The only downside is that the car must be tuned onsite. These are very impressive results. Whatever Velos is doing definitely is working.
