Well, I know for a fact I'm running way too rich. Just finished installing my wideband and I read 10:1 when I mash on the gas before boost hits in. I idle at 13.5:1 once warmed up, and in the 11-12.5:1 when cold lol.
Normal cruising is around 14.2-14.7:1 and under full throttle its is in the 12's until almost redline it goes into low almost high 13's
That's with fqs set to +3% fuel and adj fpr at 3 bar and old LR chips that allow fqs changes.
I need to probably set the fuel to -3% and do fpr that way so that it doesn't run so rich down low.

Drew turn the pressure down a little bit and see if it helps,. You are putting to much fuel and that means carbon build up.

No - do not turn down the FP. You are already way to lean at WOT; most likely knocking as well.
You are too rich cruising, and not rich enough in boost... Need to get that thing tuned, or re-chipped.

Uhmm after reading it again you are right. Lean up top. Rogue by the way when are you going to start messing up with MAF with the ostritch.

Yeah guys I'd hardly call what I have a tune! Up until yesterday I had no idea how rich I was though. I'll be doing -3 then -6% (compared to what I'm running now anyways) fuel through the FQS switch and I'll see if that doesn't help the low/middle end of the rpm. What afr should I be looking for at cruising?
Also I have a set of injectors on the way and hopefully a maf soon to fix all this, at which time I'll seafoam the car to help get rid of some of the build up.

So if you take 6% of fuel out you will be 6% leaner across the board.
If anything, go +6% so the upper revs are safe and just be richer in the mid. You will not wash out the cylinders unless you are REALLY rich; i.e. 9:1. And before you get to being so rich as to wach out the cylinder, the car would barely run from being so rich. If it is not bucking and stumbling/bogging, then it is not ultra rich.

You can not "tune" with the FQS. That adds/takes out fuel across the rev range. You need a new chip or a piggy back that can adjust fuel in specific rev ranges.

Also, if requested fuel is not being met, turning down requested figl does not neccesarily mean I'll run even leaner.
If I request 103% fuel and receive 95% it's the same as requesting 100% fuel and receiving 95% as the injectors are the limiting factor not the fqs settings. Is there even a +6% fqs setting? Thought there was only -3 and -6, maybe I have that backwards
#43
Thanks, and I don't want you to think I was saying you're wrong earlier, just that it might work the way I mentioned it. Perhaps not though as I'd have to actually test it to find out. Do you think the +6% would help to richen the top end even if the injectors are maxed? Guess I'll try that first before I risk going leaner
#45
Yeah, I thought about that. I was reading that you raised your fuel pressure pretty high when you were on stock injectors. I do have 75#'s on the way though and I'm purchasing a maf today so I'll just wait for that stuff instead of being silly with the stock injectors.
