This is a loaded question. Dinan is not making 600hp from their piggy. My flash tune doesn't even make 600hp. Don't go by advertising and what their websites say. Go by what people have done at the track or dragy with stage 1 tunes or a piggy back.

I have the Dinan for 2019M550 and it was a great breath of fresh air for my car, a solid 45-55hp over stock. My stock f10 M5 that dyno'd 504 to the wheels would slowly walk away on a 40 roll from the M550 with Dinan. 0-60 there's no competition but it's due to traction. 1/4 M550 probably still beats f10 M5 but due to traction again.
Just saying watch out for all the claims of what your reading as advertisements
