higher rpm misfire HELP!
 

Around 6500+ there seems to be a slight misfire at 10psi on a hybrid t3t4 turbo. The engine is a t2 on microtech and my timing is 18* i couldnt tell you my split at the moment i would have to check. Air fuel ratio is in the low 11's.

Any help or input would be appreciated!

lean the mixtures back to high 11s low 12s

I wil try leaning it out slowly and see if it begins to get better. I will keep you updated thank you!

hotter plugs will help as well.

Less timing...It should be fine and happy around 11.5:1. I personally wouldn't run 18 degrees and AFRs in the low 12s. Not saying that won't work though. Condition of the plugs and wires?

I am also suspecting bad spark plug wires and the plugs are newer and in good condition i pulled them recently.

I will play around some more this coming weekend with the car.
