Ok, I know there is a sticky on Stillen but I'm looking all over the place for Stage 2/3 Dyno and can't find one. I'm even searching MY350Z.com and all I see are number but no actual Dyno. Can someone post their dyno here so I can look at the power curve? I'm basically comparing both Vortech and Stillen and see what is best for my driving habit.

Thanks

 

This was while stage 3 and high flow cats ...

 

Hey Cersoft,

I was looking at your AF readings and see that you hit 12.5:1 in the upper RPMs. Is this normal for stage 4? Does your car ping at all? I'm curious because when troubleshooting my stage 3, I was lean at 12.5-13:1 and I would ping under full load. When I upgraded to a walbro 190lph fuel pump I picked up power, eliminated the ping, and AF was 11.5-12:1.

 

he's probably running out of injector if it wasn't able to be tuned out

 

Hey guys, I have the Stage II put on my car and GRD and Stillen are trying to figure out what is wrong with my A/F ratio's. Can anyone here give me insight to bring the A/F ratio down? Here is the chart.

The ones that start in the 12's are the SC and the ones that start in the 13's are stock with Stillen TD exhaust. Stillen is trying to say that my stock A/F ratios are messed up as well. Can anyone post theirs so that I can have something to compare to?

BTW, if it matters, these A/F ratios are measured via the exhaust. GRD says that they read a little higher because of the cats doing their job. Is that true?

Also, there is no sign of detonation, not that I can hear anyways.

 

based on the extensive dyno tuning that Stillen did on my car when trouble shooting my AF ratios, I can say your Stillen AF ratioslook pretty good. Sam stated 12.2:1 was best on the Stillen setup, we just couldn;t get there with the stock fuel pump

 

But what about the spike into the 14's?

 

My A/F is 11.5 now with stage4

 

My stage 2 was 11.3 to 11.7 all the way until redline. I am going to get my stage 3 dyno'd at UMS Tuning's open house on June 10th. I might go stage 4 before then but we'll see.
