no it isn't tuned yet but i unplugged the rear sensor and it is running good now ... it semms isn't there and o2 mod because the rear just needs to be out of the exhausr stream cause it reads the the same reading it causes it not to run i read it somewhere and it was just to technical to explain ..

I would put a quality gauge directly on the engine and test it. make sure your cluster isn't the culprit. My lt1 would read 20 pounds on a quality gauge hot at idle but if i plugged in the new sending unit. IT would read 5 at idle
