Re:too much boost = engine cutout
 

You need to tune it. From the sounds of it, you might actually be running way too rich. It's hard to say at this point. You really need to find out how to adjust your FMU. Since that is your only means of tuning, it's the only thing left to do. :-\

Chip the ECU and use bigger injectors. FMU is not proper fuel management. Oh yeah, get someone who knows what they're doing to tune it. I wouldn't dream of tuning a car without a wideband and/or EGT.

the fmu may be locking up on you and causing you to go lean. that happened to me before. i would hit boost and then it would bog/stutter/cut out cuz it was running super lean

oh yeah, i dont have a gas cap :-X i lost it a week or so ago. maybe thats not letting the pump build up the pressure it needs :-X :-X :P

Re:too much boost = engine cutout
 

it's happing to me also. My b18b teg is having fuel cuts around 5-6k, that's cuz my stock injectors are maxed out on that shitty fmu. But it's temporarily, untill my s-afc comes in and 450's. I know what you mean when u say the car feels like it's sputtering, it's most likely cause your not getting enough fuel or injectors are maxed. My civic did the same thing untill i went with the Hack.
