ok so ive got a 92 hatch and im runnin a mini me set up with a t3/t4 turbo and its dd at 10psi, and ive got a mbc on it and every time i turn it up to 15 psi it starts cutting out during max boost, and yes ive upgraded the fuel pump and injectors(walbro 255, and precision 440cc). does anyone have an idea why its cutting out? i really need to know, thanks.

 

God is saving your engine

 

haha shes built for boost, seriously does anyone know whats wrong? thanks

 

what map sensor you are using...if youre using the stock one it can only read up to 11 lb i believe...swap it out with a 3 bar gm one and you should be ok

 

shoulda thought of that. thanks

 

is the car tuned? did you have it tuned again for 15 psi?

 

my guess is map as well

 

it was tuned at 10psi and i havent got it tuned on 15 cause of the cutting out problem. Im ordering a omni power 3 bar map sensor today though so hopefully that will fix it then ill get her tuned at 15

 

just so you know you cant run the new map untill the car is tuned for it. I would also bet the tuner set a boost cut to keep your motor safe from spikes or noobs tying to up the boost :p
