So I was driving and everything looked average on my dashboard on tunerpro rt when the rpms on my truck's dash rose 300rpm and I heard a backfire. My blms are in the high 130's an I do know I have some blow by on my passenger side.

Hey eagle Mark welcome back man.
Here is the log btw you see the surge close to the end, I had already increased fuel thru the ve table by 10 percent I'm gonna get a new fuel filter put it and while I'm at it the fuel pressure gauge adapter to measure the pressure and see how my flow is doingDrive home from house 9-28-14.xdl
So the fuel filter was caked up with sludge I'm guessing from the gas I picked up last week, which is when the issues started. Put a new filter in and checked the pressure right after the fuel filter and its at 8psi. I'm gonna do a new tune with a modified injector flow to the new lower injector flow and catalog the results.
ell started the truck this morning and it has a very rough idle I tried reading the fuel pressure but my gauge isn't picking up anything above 4psi. Gonna take it in an hour to the mechanic so he can help me check the fuel pump and if it is then I'll get some 10 gauge wire and install the spare aeromotive 340 stealth fuel pump.
if your filter was that clogged i bet your pump sock is in just as bad of shape. might just need to drain the tank, clean the sock, put it back together...
