| 1) This is not a bragging contest, other people have made more power. 2) This is a collection of several different tunes that cover a few of last 2.5 years of results. 3) Please note A/F ratios - I am seeking advice from knowledgeable persons as to whether these target A/F ratios are too aggressive. All of these cars were tuned with the ZEM. The target A/F is 12:1 for race fuel runs, and 11.5:1 for pumpfuel runs. 4) The last few noted dynocharts are from other tuners, for sake of comparison of target A/F ratios. My personal car - first ever tuned with the ZEM.
 Orignal Z1 BB turbochargers
 Chris Damato's TT HKS2530BB
 Darren Mathews: Z1 Stage1 Turbos
 Jeff Baughmann's Z1 Stage2 turbo (555cc injectors reaching 100% duty and pulling A/F up at the top end)
 
Joe McDermott: JWT530BB w/inconel manifolds
 Joel Grannas: Sport600's, but this car had a fueling issue and the A/F coming up over 12:1 forced me to abort the session.
 Z1 Peacemaker:
 Russell's widebody convertible: run w/o nitrous, run w/nitrous
 Stage5, 555cc injector vehicle
 Tyler Duschane, GT28R
 
Here is one dynochart from an individual running an AshSPEC program, untuned.
Stock turbos, 555 injectors: Cossiemodo
Here are the reults from other vehicles tuned by other tuners.
Greg Dupree(tuner), Eizhozz (owner)
 Greg Dupree(tuner), lewoolf2 (owner)
 Rodelb (owner and tuner, AFC): Rodel stated the following:
"As you can see, it is running quite rich especially after 5k rpm. After tuning the AFC to a conservative 11:1, this is what I got:"
SGP-Kyle(tuner - AFC tuned), HogZ (owner) Sport500's (pumpfuel tune)
Z324U (Owner and Tuner - AFC)
 Andy Turpen (Owner and tuner - ZEM) The A/F is tuned to 12:1
 Timz (owner, tuner)

"NOTE: For those of you that haven't seen an air fuel chart on a dyno (I was one of them once) the lower the number on the side the richer the car is running. So 10 is really rich. 14 is really lean. I've learned so far that under boost, shoot for 11.5 This was my LAST dyno back when we knew I was running lean but didn't know why:
"
 Throughout the course of all my searching to compile this document I came across many more dyno results of which are not shown. Just from recall, there were around a dozen or so JWT programs that were showing either excessively rich or excessively lean and only around 4-5 AshSPEC ECU'd TT's that had the same problem, and a few just weren't legible (either far too small of an image, and many others without A/F plots to show). I have dynojet runfiles coming to me from other dyno shops for other vehicles I have tuned that I do not have dynocharts on hand for, and I will post a few more of those up when they come in. Matt Reed, Sean Wagner, Pete Conguindi, and a few others to note. If you would like to share your dyno results in this thread, please feel free to do so, regardless of the results. In all of the 850-some-odd AshSPEC programs I have sold over the years, I only came across that one chart from cossiemodo (using "dyno chart" as my search criteria), but I have seen many others over the times. It would be nice to see as many results as possible from as many different cars, so if you have a Z32 dyno chart, please feel free to share. :)
