Need help with Blitz FMIC

I just got my Blitz FMIC installed and the car runs really bad. Got a CEL so the car is in limp mode for now. But when I reset the ECU and run the car hard it seems that the car falls on its face at 5500 rpm. Triple checked all the piping and connections and there arent any leaks. Got a stock up and down with stock boost on a stock boost controller. Anyone have any ideas. I got the CEL codes pulled and it said that Cylinders 1 and 2 are misfiring. EGTs are saoring whenever Im hitting boost which probably means Im running lean. Is my turbo running out of breath up top?? A few shops told me that it is and that I needed a boost controller to up the boost. Would this be wise?? Any help is really really appreciated.

i would say that the turbo is running out of breath. with a huge fmic, the turbo has to pressurize alot of air to build up boost. one problem is your stock up/down pipes. in order to free up the turbo, you will need to replace atleast the up pipe with a catlesss one. i would go that route first since it is the cheapest, and will add the most performance. how long have your spark plugs been in?? i missfire cel is usually caused by fouled plugs, the colder intake charge will allow the ecu to run more timing, thus running lean. but since you are running stock boost, i dont see that lean would be a problem.

i would reccomend running 1 step colder plugs, and changing the up-pipe.

good luck

well an uppipe and plugs will help but its not going to solve everything. your ecu is seening the f/m and it doesnt know whats going on your going to need some type of engine management and a well tuned map to make everything run smother. It sounds like your running way too lean you need to change the injectors and you need a fuel pump. what made you buy the f/m your not going to see any improvement over stock with just a f/m you need a upgraded turbo and all the supporting mods then youll feel the differnce

well good luck
