at speed racing Rolling road in Rayleigh Essex
Discussion
Well I just got back from my rolling road dyno tuning at ATspeed, and it all went very well.
They have modern equipment, good facilities and the guy knows what he's doing.
Obviously my car was "old school" tuning, carb with no ECU, but got a good improvement.
He said they also do modern engines and ECU remapping etc.
I'd happily give my recommendation.

Took the racer there Sunday
Good new it was not far off and running in the safe zone, apart from a few high and low spots.
Bad news They could not get the emerald software to run on there laptop, good job I brought mine, also they was not that up on using the emerald software (they did knock off an hours time though due to there problems)
End result up about 10% across the range, was running 175 BHP at the wheel (at 5300 RPM) before and after 190 BHP at the wheel, so about 230 at the fly, which is about as much as your going to get at of a 4.0 running standard heads.
Also should be a bit more responsive as they spent about 2 hours just sorting the 2k to 4k RPM range. so its got a much better curve.
other good news, the emerald temp sensors are over reading so the car is not running as hot as I thought, will have to calibrate them manually.
Very nice bunch of guys, seem to know there stuff, but could have been a bit more honest on there experience on mapping the emerald ECU

Why do all these places only have 2wd dynos. 
I know TDi can do 4wd but don't like the idea of the hub dyno. I only want a power run, any other places in Essex that can cater for 4wd?
Some people have said the hub dyno's are better, any reason for not wanting to use a hub based system.I know TDi can do 4wd but don't like the idea of the hub dyno. I only want a power run, any other places in Essex that can cater for 4wd?
I think most people still have 2WD due to the price and also most race and track cars are still 2WD. also its not if they can be upgraded.

Similarly any dyno print out from them is less likely to be accurate (again due to resistance from the wheels) and also if diagnostic work is carried out them it may not show as much as if on a normal RR.
Apart from that I don't like people taking my wheels off. Had one come loose once after balancing. Never trusted anyone else since even though i check my nuts (ooo err) after any such event.
Makes sense about most race and track cars being 2wd.
I thought on both systems they would have to add some resistance, as on both systems there is no drag (wind resistance).
I agree with lots of people not being able to do up nuts up correctly, they either do them too tight or too loose, or do not do a progress tighten in a star pattern.

I used ATSpeed for my Volvo Amazon back in 2008.
