I made a post over on 6Club with some DashHawk logs. If you guys can, check it out and give me some insight. My car is insane....

i see a bunch of pretty colors...lol

Rich, I honestly dont see anything MAJOR with those logs. Fuel pressure bounces around a bit, but no obvious fuel cut, afr seems really good..

I think you need to log with the standback so you can see what your boost looks like. Its difficult to determine if you are getting fuel cut or boost cut. Those logs dont show any fuel cut, and you cant log boost cut with the Dashhawk, because as you mentioned, the numbers are skewed...

No obvious fuel cut??? Look at the RPMs! 4th Gear run, load dips and AFR spikes.....fuel cut bad.

Rich, fuel pressure would drop completely with fuel cut, and that isnt happening

Hmm...well it's a something cut. Car jerks pretty hard, like the RPMs show. I'm pretty confused....my fuel pump looks to be alright. It's the dips in Throttle I don't understand, and the spikes in load just before cut.

thats what im saying..log with the standback, and log boost, id bet anything you are getting boost cut... which should be an easy fix...

I'm set to 14 psi. I'm only spiking to mid 17s. I've run more boost before without any issues. I'll do some standback logs tomorrow.

the Absolute TPS is kinda funky on the last log...i wonder why it dips in the middle like that...is that your cut? the load spikes are the obvious cut spots, but the fuel press doesnt even match the cut spots, so I would possibly rule out fuel cut. If the damn dashhawk would read accurate boost, we could have more of an answer....but it sucks, so it doesnt

The RelTPS and AbsTPS dip. The Actual Pedal position shows what I'm doing. I have no damn clue wtf is happening.
