02 Z06 with 150 shot jetting question When i had my nitrous outlet 78mm plate kit installed on my 02 Z06
.... I noticed it was running really rich. What would you suggest? I currently have the suggested jets for 150- n62 f38. should i drop the fuel to 35 or 33?
i attached the dyno graph...the top run is NA, the middle is 150shot and the bottom is 100shot.

The shop said they pulled 9 degree's of timing. I thought it was low too for a 150 shot.... I want to get the MSD timing twister in the next couple of months and have it re-tuned. what numbers are you putting down Sarge?

Well you have a decent size cam like I do and I pulled 9 degrees and I'm around 17 at WOT on the bottle. I use the resistor mod to pull my timing based on a table in the PCM only during my nitrous runs. You can't really trust a specific timing number to pull. You need to read the plugs. I would say your running a safe tune but some left on the table. Need to read plugs to know for sure. What plugs are you running?

I haven't dyno'd it on the bottle but I'm 467rwhp/430rwtq on motor though. I'm skeered of the dyno and nitrous...
I just use the *** dyno and data log. I also run known dyno'd vettes and see where I sit. I've beat 620rwhp SC'd C5s so I'd say I'm getting a good portion of my jetting out of it.

Yes car is running great. Having an issue with my NGK AFX wideband with the NTK sensor. At WOT it reads as low as 11.3 AFR. The LC-1 I just removed and 2 different Dynos showed 12.8-9 at WOT. Can the bosch sensors be that far off or is the NGK wrong? Narrow-bands were in the 960s to 980s at the same time the NGK was at 11.6. The NGK is suppose to be the best consumer grade unit but...
So I gotta figure that out.

I had to go to a 28f 62n jetting to get my afr to 12/1 on my nitrous outlet 78mm plate. My car made 366/425 N/a 477/561 150 shot on 25* timing not really sure why I only gained 110 rwhp on a 62 jet? Maybe the Yank ss4000 soaked alot of it up?
