I had a simular problem in my CRX.. Had a misfire for months, Couldn't boost over 11psi and could'nt rev past 6k.. Changed everything (almost) New coils, closed plug gaps, warmer grade plugs colder plugs, Data logging ect.
Then borrowed a set of HT leads and it cured it Rev to 8.5k and boosting to 16psi... I felt pretty stupid after all that lol
Glad yours is fixed
