Last time up on the dyno I was right at 470/940. Today didn't go so good at all. I was 425/826 today... I'm going to check the lift pump pressure and change the fuel filter.

Only differences was an updated program on my Smarty. Same dyno, similar air temp, same everything else. Boost pressure was normal. And water meth that showed zero power gain. Something wrong there but that is another thread.

 

Having worse problems. Truck is loosing power. It will build boost but is not getting fuel. It won't smoke at all. I'm thinking the fuel pump is gone. Might be getting a Fass.

 

when i lost power and wasnt getting any smoke it ended up being my OFV. yes i know it a different pump and motor but esentially itwasnt getting fuel. new ofv and a lift pump, the latter perhaps not even being necesary fixed that.
