ok so i bought a 2010 impreza turbo diesel and i want more power without spending more than 1000 pound but what is the best value for cash solution. ps i know its diesel and i should have got a petrol but i like the cheap insurance plus the mpg currently ****ing on 149 hp as standard. any advice?

 

Remap and look into the air intake

 

Remap is the best value for power on a Diesel engine. For example, my "normal" car is a Vauxhall insignia 160bhp diesel. Can be remapped to 212bhp with enough torque to spin the earth backwards for £350!
