...still awaiting my wooden spoon for having the least WHP whilst an auto on the dyno day. :P
Let's say the auto box losses were greater than 15%. :-k #-o

I can explain it, but I can't understand it for you.

The car drives well, only real issue is the a misfire kind of feeling around 4-5k rpm mark that Bridgeports seem to make.
Done some gps runs using draggy for 100-200 kph and it's done it in 16 seconds gps
It's as fast as stage 2 mk6 gti,
Faster than full bolt on Mugen dc5 type r without a map

They do a calculation of hp x 1.15 to get the fly HP so around mid 250 range
One of the things on my list of things to diagnose and sort is also a cough/misfire always between 4-5k. Even on light/medium/full throttle I usually get this misfire, no fault codes but a repeatable misfire. Also a slight hesitation up around 8k. Mine is standard engine by the way but has been custom tuned with logs (it actually seemed to be start happening around the same time as tuning) so I wouldn’t just assume it’s a “Bridgeport thing” and go through the logical and systematic troubleshooting as anyone else would.

That's what I've been told by rr, it's how the Bridgeport is cut
I've showed rr and they said it would take too long to fine.tune.it and remove it.

Mine only happens on light throttle, otherwise it's seemless throughout the rev range

I also get a very slight hesitation on going through 4-5k rpm with my bridgeport on light throttle. It's not noticeable on medium/heavy throttle and therefore does not impact on track driving ;)
