Hello im Dan from Norwich,
I bought a Astra 1.8 Sri about a year ogo as a practical faimy car. I really like the Astra but as our little girl is a bit older now i thought id change it for something a bit more fun. I looked in to tuning the sri but for the power i wanted was really expensive so i got the GSI, Ive never owned a turbo before so i dont really know what to expect from it. Ive ordered a DV26 baily dump valve and a few cosmectic bits. Any one got any advice on simple engine tuning or what to expets from a zlet?
