Is your tune using speed density ?
what is manifold psi with ignition on but engine off should be close tovatmospherix about 14 psi
if its an NA car on petrol with stock injectors and map sensor load a stock tune on car do you still get misfires ?

Stock tune I still got misfires.
Tuner attempted to help fix the issue by making idle 900 RPM and turning off the CELs for the header since it’s PTUNING without cats.
Other than that it’s basically a stock tune.
It’s 91 NA
