Hi ppl, new here, have an astra gsi 2003 model. The need for speed has overcome me and i am now looking to have the engine remapped. Vauxhall's, or rather vxrperformance centre in oxford will remap it for me taking it up to 250BHP and jus under 300lb torque. To do that is £480. I have heard of regal and superchips. Has anybody got any experience of these companies. Obviuosly i want the most for the least amount of money. All i want to do other than that is fit a SS exhaust system.
What do we reckon?
