Hi guys...
I have a problem with my car, in that if i give it full throttle, it runs worse / holds back compared to half throttle... the pump is an 11mm conversion....
Is there any chance, that my modifications to the levers for extra travel, is causing the collar to travel to far, and acaully nick some of the start of the injection, causing a retard in timing under full throttle? Or is it impossible to move the collar far enough for this to happen, it just builds massive boost, but feels to be holding back alot... i have a lift pump in the tank also, but with an inlet - outlet one way bypass in the engine bay to prevent it pressurizing the inlet side of the pump...
