questions about a/f and tuning, bad dyno #'s
I ran my car on a dyno this weekend, I can't scan in the graph but in short I was disapointed.
t3/t4 .50 ar
7psi
2.5 in exhaust
b16a in a CRX
Intercooler
VAFC hack
450cc injectors
car ran 153 hp and 140 tq
It was 95 degrees and about 90% humidity
I thought my tuning might be off but my a/f ratio started at 13.5 and went to 12.5 under boost. IS this right? Plugs are not white look sorta black/brown
Gap to .032
What to do now?
Compression was 200 all the way across.
I did have a bad injector in #2 that was causing that cyl to run rich, I changed it but still I should be much higher!
Any help is appreciated.

something is definately wrong. my d16y7 tuned originally at 5.5-6psi got 145whp and 138wtq on a smaller turbo. did you fix the bad injector and dyno again or was your best dyno run with all 4 good?
