450whp FC turbo sputtering

my fc sputters and wont make peak boost at about 4-5k and will sputter and bog the air fuel ratio goes up and then shortly after it hits boost HARD and it has done this and then stopped 3 times now and it spits alot of fire while sputtering and I would like to know if it's minor or serious, doable at home or should i take it in, and how to do it. Thank you

If you have a highly modified FC and you are asking HOW to tune it,then no offence,I would take it to someone.
Don't be shy..and foremost do not be embarrassed..ask questions..!
I had a 357hp FC and I got a tuner to do it.I didn't know **** and I didn't want **** to happen.I can wrench but know squat about ECu's
The best way is to let someone that knows work on it.If they want to teach you then that is a bonus.

i just took it in and had non engine related work done and am now broke... I think it could be as little as a spark plug or a coil or even a bad injector maybe even a valve getting stuck

that is the thing.
A tuner will look at the engine's logs while it is doing that or with the running and can diagnose it.
Broke?..aren't we all?..it's a Rotary..it will make you bleed green!
