Verdad Gallardo Oh, ok just throwing that out there then. The sender and filter is removed when the cam is swapped out? Is that the part on the intake that gets blocked off? Mine is all stock so I really have not looked into all that yet. Thanks
Edit: I looked it up, I get it now. But is the sending unit relocated down near the oil filter now or somewhere else using adapters?

Ok the reason I ask if the wiring had to be extended that could be a connection problem. I would start looking at that since the sending unit has already been replaced. If its still in that general area then probably not but if the unit was relocated down low near the filter then the chance of a bad connection somewhere could be greater. I am anxious to see what this car will do on the dyno, as I am sure we all are. I hope this is resolved quickly.

It's mounted in the factory location plug was dry roted when I did my transmission about 6 months ago I put a new plug on it and connections are soldered and heat shrunk I also have a fresh oil pump in the car and I had this problem before when I used a Delco filter and I have a Delco filter on it now
