hey guy i am trying to get the car to pass inspection and i have had it street tuned but i need a good dyno tune any recommendations thanks
if you have a solid street tune, you will pass emissions. They dont push your car to the "high" maps during inspection.

the tuner i am using is a apexi safc neo and im not to sure about the tune it feels good but never has been dynotuned
you need to drive the car around at low load situations, and use a wideband to get the car to run with an a/f ratio of ~ 14.3-15.0:1 at anything under 15%-20% throttle. (basicly any time your not in boost.)
what i did, was to watch the boost gauge, and use the one of the displays on the SAFC to display throttle position, and figure out how much throttle i had to give it before i would make boost. in my car, it was ~20-25% so i set the hi/lo throttle cutoff at 20% for the lo and 30% for the high, so that anything below 20% throttle was using the lo throttle map, and anything above 30% throttle was using the hi throttle map. (the SAFC interpolates between the set points.)
then drive around and watch the wideband below 20% throttle, subtracting fuel till i saw at least 13.5:1 in the lo throttle map, and tuned on the dyno for the high throttle map shooting for ~11.5:1
