Saturday I'll test the fueling situation and change the oil. I have low expectations.

Sunday I'll swap on the snow tires. Not having a TPMS light will be a treat.

I made a couple quick pulls today and the fuel pressure behavior didn't look too bad.

I've decided to make an appointment with Ron @RS for an hour of dyno time. We'll test it out and I'll get the opinion of another guru if it doesn't look right. I'm going to see if I can get away from work on Friday afternoon for that.

Is the hand healed? I imagine there'd be no "personal time" for at least a week with that type of injury, lol.

haha! Yesterday was the first full day without bandages. It looks bad but it didn't prevent me from typing (work) so nbd.

I've been single for 4-5 years now so I'm pretty resourceful. :D

Haz fuel? Ron did a half-dozen pulls on his dyno this afternoon and the new pump looked good to him. He added some fuel up-top and the AFRs responded as they should.

He is suggesting that my motor is burning oil because my catch can arrangement doesn't breath well enough (the motor is tight or needs more airflow). I'm going to try changing that up as he suggested.

I'll go back in a couple weeks and we'll try to turn up the wick. 437/366 on his dyno as it sits.

So we had chatted about power source and/or grounding issues(quick/easy/cheap option). Or the pump as the next to check. If this fixed it.. Congrats!

Yeah, I experimented for a week with ground locations and I ran a wire from the engine bay and it didn't seem to help. As soon as I dropped this Jay Racing 044 in, fuel pressure looked well behaved--I was able to hit 68psi on a couple pulls on the trip to Rock Falls last weekend.

I guess the real test will be when we try to add power.

Thanks for your help!

So it leaning towards the pump as the problem?

437whp at ....less than 23psi? Holy eff that is awesome!

Time for more boost and see if you can put all this fuel system bs behind you! Good luck!

This Jay's 044 has behaved better from the start. The original 044 wouldn't reach full psi half of the time, it'd go to 62 instead of 68+ psi.

Yeah, it spiked to 25.4. I normally wouldn't be happy with how that boost curve looks but the car hasn't really been tuned. Spool is sad but mivec hasn't been touched for the cams.
