Been to Dales, Bailey performance
Not particularly lowcost, my DB7 i6
A few years ago I fitted an emerald ECU as the factory Zytec is impossible to access without special software and has limited control, mixture and RPM
limit.
The car is lightly modified, smaller pulley on the supercharger and free flowing exhaust, I originally took the car to emerald, after a few hours on
the rolling road it running well with figures of 385bhp/370ftlb torques  all good although has always struggled on emmisions and needed to turn a
few times before starting, figured that's how it should be.
Last year I started looking at the ignition mapping, it was still on the default ,as they had loaded from a jaguar XJR6, 800cc larger capacity less
boost... 16 degrees advance at WOT.. Not great so 1st January tried advancing the ignition which lifted the acceleration by around 10% but went to far
and blew the head gasket.. Balls.
It's taken me 4 months to address this, I purchased a brand new fully built head, factory old stock and had ported, valve inserts opened up by
~1mm under the valves and the small exhaust ports opened right up, time for the rollers so booked up with Dale.
Upon arrival the maps were inspected, really jagged, Emerald has boost compensation table that backs off ignition and adds fuel that runs with the
main tables but even so ignition and fuel look wrong on the graphs so Dale opted to start again rebuilding all the maps and removing compensation for
negative pressure then off to the rollers.
6 hours later on, the car starts immediately 1st turn hot or cold, idle at 1500 rpm that drops to the correct 750rpm with no need to touch the
throttle.
Driving up the road throttle responsiveness is greatly improved with a very flat torque from 1500-7000rpm, before it felt slightly flat under 3500rpm
at WOT.
Ignition advance has increased, I think it's now around 21 degrees - Dale tried a little more but no gain in power so it's to the sweet
spot, ignition and fuelling maps look quite a bit different to the one before, smooth and even when looking at the graphs.
Power by Dales roller is however down 349.5bhp 320lbft torque, not a concern as the only clock that counts is on the finish line, maybe Dales reads
low or Emerald reads high... Thinking probably the latter.
So on the road, from idle to WOT the car is very different to drive, touch the throttle and it launches itself off any gear, jam my foot down and
it's never been so fast, low and mid range much improved so I can trundle around in a higher gear and it's much smoother at all times,
quieter as well!
I'm sprinting at Blyton in a couple of weeks, I expect to be a couple of seconds faster as it feels that much better.
Anyway highly recommended, travel the distance if you want to ensure attention to detail and a good result.
Cheers
Mark

As you say, figures are just figures. The proof is in the times.
Do Bailey do OMEX?
Track days ARE the best thing since sliced bread, until I get a supercharger that is!

Dale will do anything, okay a broad statement as he would not be able to do the Zytec original ECU on my car as it needed bespoke software and the
Aston Martin Dongle so lets caveat that statement, anything provided you bring the tuning software
I did see that he has a load of different software on his laptop including OMEX, but if you think it's odd just take your laptop with the
installed package and I am sure he will sort you out
You are paying for the attention to detail and you book a day of his time, but better to check with him directly of course, very nice person to deal
with.
Note, I do not have an axe to grind with Emerald as the car was good when it left them and has performed faultlessly, it's easy to frig rolling
road figures and Dales may read low, it's all in the driving as a car will always perform differently in free air.
Cheers Mark

No first hand experience but I was under the impression emeralds equipment generally read lower than most.

Emerald had a new rolling road installed a while ago I believe?

Emerald had a decent road when I was there, electric eddy current and I was lead to believe that it was an accurate one - as in not ambitious
numbers provided, my car was rated by the factory at 325hp and with the driving dynamics package 385hp.
Provided the rolling road measures improvements on the day from wherever you start to wherever you finish its all relative anyway, my cars never been
so fast is the bottom line from tick over to WOT.

I'm the same as you,not a bad word to say about Dale!
When he mapped mine last week for instance the inlet manifold was leaking,so needed to come off.
Let's you use all his tools,even helped and cleaned up the lower inlet manifold for me!
Lots of mappers would have been kicking me out of the door with issues like that,to get the next car in.
You get his workshop/tools and a whole day of his time for a really good price!

Dale,
Where are you based? I tried looking on your website, but couldn't find an address (but maybe I didn't look hard enough).
