Default popping/backfireing/ inconsistant rpm increase from 6k-7k

hey guys,


set up is, 14 b turbo 9.5psi jrc 5" fmic dsm 450s and afc hack. stock d16y8 motor.

i get to about 6k and and the motor kinda back fires and spits till 7k(redline), it still gethers there but from 6-7k the rpm increadse is inconsistant. my settings are from 5-7k -35 in wot. any ideas? i thought it could be the plugs getting fouled up a bit, i have had them on since the head gasket went out and while the head was lifting so they could be bad. thanks for your help!


Nate

i had this same problem...that and for some reason i couldnt run vtec while turboed until it was tuned. if the plug gap doesnt work, try unplugging your vtec silinoid and running it like that.
