A 40% increase in power from 75 to 105 is definitely worth doing, I wonder how much the 90bhp version could gain from a remap.

Probably not as much as you would hope, someone correct me if I'm wrong but the 75/90bhp 1.4 N/A engines will be pretty much the same hardware and just limited via the map on the ECU? So both will remap to a similar level I would have thought, regardless of you having 15bhp more from the factory to begin with.

1.4 75 and 90 are identical mechanically, simply an ECU restriction - 75 delivers 75ps between 4200-6000 rpm (4200 rpm is also where the 90 delivers 75) then 90ps is delivered at 6000 rpm on the 1.4 90.

I imagine the 1.4 90 will chip to exactly the same amount as the 90... So for the price of a 90 you could buy a 75 new and pay for it to be chipped - if you don't mind warranty and insurance implications :D

I'm from the Corsa E owners page, I paid £170 for my 1.4 75hp engine to be remapped to 105hp. Feels like a new car! I fitted 30/30 springs on it too and reduced the PSI of the tires all round to improve handling with the extra power :D
Where abouts did you get your 75hp remapped to 105 as I’m looking st doing this aswell and I can definitely justify that price for an added 25hp unlike some that I’ve seen which are £249 for only an extra 8-10hp!
