Bit of and update..
Thought I Had a bit of a head gasket scare! Basically was loosing coolant without any leaks and as I have already bypassed my heater core it had lead me to believe possibly I had done the head gasket! Went through all possibilities before jumping to the worse possible scenario and found my return hose clamp had come a little loose from when I swapped to silicon and was leaking coolant under pressure! (biggest sigh of relief!)
On a even brighter note just picked up my 255 Walbro fuel pump curtsy of Evolution R and just received my Grimspeed 3 port boost solenoid! now just waiting on a silicon inlet pipe and my new turbo and off for a tune!
Have decided instead of ASG I will be taking my car to Evolution R for a tune, mainly the fact that I have dealt more with Mao than any other workshop, and find all his info very helpful.
will keep you posted on the tune results
