Turbo splutter on boost please help
Turbo splutter on boost when you put you foot down hard but fine when driven normally. Only running 0.3 bar boost. I've been told it could be the fifth injector but unsure if this is the problem but it's running standard ecu with adjustable tuning box thing for the fifth injector basically what I wanna know is it best to rip all this fifth injector stuff off and get bigger injectors and another ecu like predator as I know of all this going at a good price that came off the same car. The car was only converted a few years ago by cituning but my problem is they are about 5 hours away. Please help

Have you checked all the boost pipes? Sounds like there may be a split. Would run fine on low boost but under pressure would leak.

it could be anything --too lean or too rcih --so gat it diagnosed properly to satrt with --but yes a stand alone or predator is a better option anyway
