Hello people, i have a prob wit my s2, ill fill u in on the spec first of all!!!
Recon bottom end less than 8000miles with ARP bolts, recon head also about the same milage kent cam, double valve springs, standard turbo, -31, but also recon, Bleed valve ,bailey dump valve and KnN and full scorpion! The ecu which is on the battery side of the bay has a "Superchips" sticker on it?
Ive only had the car three weeeks so im unsure as to how true the spec is

I had the timing done last week and the boost set to 10psi, as previously it was shockin!!!
With the timing sorted and boost set up it was perfect and i was more than happy with it

I took a trip down to work in cornwall which is about 80 miles from me and ever since its been shit to drive?
It sometimes pulls fine and then it sometimes feels like a snale is quicker :Any advice please
