Ok thanks mate, defiantly looking into one now. Bumped into the manager of X-sport Racing and he said megasquirt are good and that they will map it for me, just need to know where the best place to get one is!
rossbarry im pretty sure it would work but as was brought up by rubjonny there are engine management issues but seem easy enough to get over! Dbilas dynamic are heavily rated in the Vauxhall community, a freind of mine had one on his Astra SRi and it did have a big improvement in torque was noticeable through the who rev range.
I will let you know how i get on over the next few weeks! i'll get some pictures posted too.
