I would pick them over autotune though.
Autotune have a dyno @Colin organised a day at it. Had the Megane on it.
Did you just remap or did you have any other mods?
Uprev, Nismo Exhaust, HFC's, XYZ Pipe and Intakes ... Made some difference but not enough to warrant the guts of £400
Id just take it to Autotune. They will leave it with a sharper throttle reponse and a bit more power.
My zed was 2008 so it was the dual throttle HR engine.
However the DE and Uprev engines tune better ... still not huge gains but will see more than an HR engined zed.
I dont think headline BHP increases are the way to look at it, as @dingle has said, driveability, if it smooths out the torque curve lower down the range, moving off, overtaking without having to drop a gear etc, id pay £450 and accept it isnt going to make it much faster on paper but feels better to drive.

That only shows a full throttle pull in 4th gear though matey, switching lanes in 3nd gear in low or mid revs wouldnt show on that basis. NA cars are generally lacking in torque low down and a few extra lbs can make a difference instead of dropping a gear which takes that second when you could already be on the manoeuvre.get a before and after rolling road report and over lap and then you can decide if it was worth it
Only thing I can maybe compare it to would be maybe like in a e46 m3. Like sport button and normal driving. Some difference in throttle response in them from a different map switching between them
