I have a car with a fairly basic petrol engine. A quick look on the internet suggests I can achieve an additional 10hp for £150 (this was a pre-xmas offer). I know its not going to set the world on fire, however the car isn’t doing amazing MPG and I’m sure the 10% power increase will make a bit of a difference too.
The car is due a fair bit of work in a few months (service, cam belt) so thought about trying to get this added to the deal and get it a bit cheaper. This car is going to be a keeper as apart from the poor fuel economy its in good condition and should be good for another 5 years and we owe no money on it.
I am aware that they can achieve different things with the re-map but is there a rule of thumb that would make it worthwhile, ie <£1 per ho / 1 mpg increase? I’m hoping that a good person can achieve extra power and mpg for about £200.
If anyone can recommend any good mobile or Sheffield based people that can do this please let me know.
