Default Running just a teensy bit rich...

Dyno'd my '99 T/A today. First run was N/A, second and third were on a weak 100 shot.

A little rich, I think. Is there anything other than tuning that would cause me to run that fat? I had it tuned a little to compensate for the nitrous, but all the guy did (as far as I know) was take out 3* timing.

Also, how much power do you think this issue could be costing me?

My god man!!! You could probably kill small children standing too close to the car based on just the fumes.

Shoot for around 12.5:1 on the juice and you should be fine.

Do you see raw fuel dripping out of your exhaust pipes. Only thing good that can come out of that is when someones tailgating you and you floor it and leave em in a cloud of raf fuel.

Both! The N2O didn't lean it out any (that was visible on the graph, anyway)

Going to talk to my tuning guy on Monday


EDIT:

Nope, no fuel dripping.

I spoke with Tony (my tuner) this morning, he says he didn't touch anything other than timing. We're going to run some diags on it tonight.

Ryan, check your O2's and see if they are OK...Man with those A/F's even NA you could run a 150 dry shot and be alright j/k...but check your MAF and O2's...those are the 2 main things that control A/F ratio.
