So a customer drops his car off for an AEM tune

500 is a nice number.... You thinking about 530 when she done? Just a very uneducated guess.

Engine is getting noisy and the meth injection doesn't help and timing is in line. And since I didn't build the engine I am not going to push it.

Graph is a little more shaky than previous as I made the JPG of it with smoothing at 1 instead of 2 like I did previous.

18psi 498HP and pulls real nice and hard and smooth.

So is full boost at 4200rpm the norm for TD05 turbo's?

Real Talk!

When I was installing my twin 400 pumps, my sender looked like a dirt/rust hat on top of my gas tank- all the wiring and terminals were corroded to balls

Nothing a wire brush, and some plastic media blasting couldn't take care of- though the terminals needed to be redone with gromits and new wires completely as the wiring was corroding off the top of the hat and causing iffy voltage to my fuel pumps.....

Northern salt sucks.......as do the occaisional -20/-30 temps in the dead of winter.

IPS SS fuel hat. Mine was rotted to shit. I wasn't going to deal with that again. Now I have a 316SS fuel line, Nylon Braided line and Aluminum fittings connecting the fuel pump hat to the fuel filter. Nothing left to go bad EVER....minus the return and the breather....which are almost gone from rust :/

OK,

Reinstalled the boostaspark, and reinstalled the AEM Water/Meth kit. It was installed with the tank in the hatch and the pump in the engine bay which is a no no. Plus the pump was higher than the tank, another no no. Plus the wiring was done with single strand housewire (as was he boostaspark),wire nuts, scotch locks, and the ignition/on power wire was dead.

Got is all installed correctly, tank in hatch with pump right next to it lower than fluid level at the fluids lowest level. Primed/tested with no nozzle/jet attached. Pink gook was coming out of the line. Got that all purged out. Checked he steel mesh screen on the nozzle/jet and it was totally covered/clogged with some pink gook. Cleaned that. Put nozzle/jet on the line and tested, a nice fine mist. Check.

Tuned it until the fuel pump ran out. No matter what I tune for anything past 20psi she runs out of fuel. PTE 680s with correct base pressure and Walbro 255LPH HP with Ninja Performance hot wire kit that I installed. It's just out of fuel. So I backed it down to 18psi for safety. Has a nice smooth and long power band. No knock and I leaned towards conservative on the knock cal table. Then again, there are no spikes on knock volts or knock raw. Quiet as a mouse.

Here is the final running 18 psi pull.

So you lost a little HP but gained around 50Ft\Lb's of torque.

I was looking at Trevor's fuel injection sizing data and it seems 680's would be able to handle more HP with higher fuel pressure.

I am assuming it is a fuel pump issue?

Your thoughts.
