Thanks to a bit of Trackcar magic my car has joined the 400+ club 
It went in as a standard 4.5, and put out 362bhp and 340lbft of torque - not too bad.
Joo fitted his whirlwind induction, full Silverstone exhaust and remapped the MBE, to give 410bhp and 350lbft.
Drove it back to Surrey this afternoon and have had time to reflect on the changes. I can't decide what I'm more impressed with, the performance or the sound. The SP exhaust sounds incredible, hard edged, racy but refined with a slight howl, not unlike an Aston IMO. Fantastic. As for the performance, the figures don't do it justice. Over 4krpm it really flies. 4th gear on the motorway is devastating
Big thanks to Joo for his efforts (and coffee)
. Needless to say I'm chuffed to bits.
There's a gauntlet for you, Russ, Joo tells me you're next...

410 
...... Ouch...... 
I'm booked on the 8pm train home, so I'll probably spend a late afternoon drinking & eating in Chesterfield
I've just left Simonkd
in the pub, and I think he'll be one of Joo's next customers.
Rog, what's the score with the cats on the SP system ? In, out..... Shake em all about ?
Did I already say "410" ?????

" ????? The SP comes with linked decat pipes, everything from the manifolds back. It's well made too (I'm starting to sound like boss) with hefty flanges and tank-like rear box construction

Out of interest, what's the rough cost of all this work.
- Roughly* £1k or thereabouts for initial dyno run, supply and fit whirlwind, remap of MBE on the dyno (a day's work well spent) coolant fan mod (if wanted), road tuning for drivability and an implicit health check/diagnosis of anything untoward. Not including anything found during check of course, in my case a new throttle pot and throttles balanced. Joo also fitted the exhaust for me. The exhaust itself is another ~£1k from SP. As others have said, money well spent.
- well done Rog . . . about the same as mine then

Nice to meet you! Are you two going to be betting on who's going to end up with the faster car? 
Yea, good idea. I'll bet Russ £50 that mine makes more power, and I'll bet you £25 that Russ wins.So Russ, you owe me and Joo £25 each
(unless you want to up the stakes)
I can't help thinking that deal doesn't work out very well for me
I'm not confident of my car beating those figures of yours Roger. Based on my figures last November, I reckon I'm about 20bhp/10flb down on your start point and that was with nearly new hoses...Does it sound like I'm getting my excuses in early ?........
That hotel opposite Chesterfield station was in surprisingly good condition, I am from B'ham after all

Reading threads like this makes me want to book mine in ASAP, but then another part of my brain says why?
My car drives really well, isn't lumpy in traffic and pulls hard in every gear. It has just had a new ECU and some mapping work at TVR power so would I be wasting my time? Perhaps the 1k'ish involved would be better spent on suspension/brakes or go into the emergency fund.
But then I see a pic like this and I wnat to book in ASAP again, sod the power gains:
