Had the above re-map done at MPG the other day.
Turned out more expensive than I thought, but woth every penny. Car now is completely different. Obviously it is faster, more than I thought it would be, but it is the way it goes that is great. The power is completely useable. 1st and 2nd tends to get the wheels spinning wet or dry, but once it gets going it is certainly impressive. The power is spread over the rev range much better and doesn't just run out after 4000rpm. If anybody reading this is pondering whether or not to get a re-map. Get one. Regardless of who it's made by. It turns the car into a beast.
In all, I love it. Best £500 I have spent in a while. Ian at MPG is very helpfull and for free he removed the restrictor on the top of the airbox and found that Arnold Clark had fitted the air filter for the Astra which is too small. Horay for AC!! Going to start saving now for the Diblas air intakes from the airbox to the turbocharger (much larger) and de-ristricted pipes from the turbocharger to the engine inlet. Then full exhaust system. K&N panel to be fitted next month.
Anybody in the NW fancy a rolling road day somewhere?
PS, to Andy W -sorry I never got back to you re. a run out in yours before I bought mine. I have a baby on the way and have been in a mad rush to get the house ready and got the map done just when I had a minute!!
