It's hard to say, I've tried looking into this vehicle and it "may" have also had an 80mm TB - emphasis on "may have"

Other definite mods on it that I have found were deleted secondary cats and X pipe with straight trailing pipes, factory headers

Also the temp while dyno is on 13 degrees celsius so nice and "crisp" outside to say the least and not 100% on what fuel type was used and tuned for

But yeah that is one hell of a gain, most of their tunes seem to net really big numbers and I am wondering if it is just a really generous dyno?

For example, I know a guy here in NZ who put an 83mm and shorty headers on his E55 and with a custom Dyno tune got ~465whp

Where the tuner above off a stock motor and just an 83mm SC pulley seems to net around 470-480whp consistently from what I have seen off a fair few E55s with just a SC pulley through them?

I hope someone else puts up some other dyno numbers from the 77mm soon

I am definitely going to get one when I can, no ifs or buts

dynos are more used to measure gains and test tuning than they are output from car A on dyno A vs car B on dyno B. You can manipulate the crap outta numbers on one.
