boost control and retard timming on boost

[ashnery]

I dont think I have blown a head gasket.
how muich is a tsi control?
my motor is from pete at petes pit stop (his personal bike)I think its running rougth for he has removed the water injection without(telling me)... remapping and there is no intercooler(mind you I dont think you guys run these)The motor has a plate and pistons, the pcIII I have is only for fuel nothing else.
With a turbo system when the engine is hot say above 90 deg does the motor start to miss on boost??
