Hi, a workshop is changing the engine in my st205, and they have given me an offer to change the ecu to a haltech stand-alone and remap it for a total of about 900£ extra. Do you think this will be worth it? They will be putting in a Spec stage 3+ clutch while they're at it.

Technically the mechanic is right. Really shouldn't be below 2k RPM when driving or else pretty much ANY car will bog down.
As far as your AFR... that should be 14.7 unless you're boosting so you are running extremely rich which can cause other problems down the road besides terrible fuel economy and lack of power down low. The car running on a standalone should react pretty much the same as on the stock ecu up until 3k when you hit boost, and should destroy stock mapping from there to redline. Under a proper tune you should actually be getting better gas mileage (obviously with normal driving characteristics), then you had before the setup was effectively optimized and it's full potential was realized with the standalone.
