boost cut ???
hey guys i have just finished my first conversion with stock rs donk with a tdo5h, 99 tmic, bosch coil pack, 02 sti tbe.
so whats happening is when i get to around 3000-3500rpm i come onto boost around about 5psi then get to 4000-4500rpm on 10psi and it will either loose power or completly cut out like the car has stalled so i obviously pull the clutch in at this point and back off. ??? and whats weird as it will boost perfect 10psi for first 5mins then start to do what i have explained anybody got any ideas of whats happening ???? cheerz,james |

Check your spark plug gap (0.8mm) and check fuel pressure and fuel filter.
Also clean the AFM and reset the ECU.

i have had it just straight wastegate to comp , have used stock boost controller, but now im using a mbc turbsmart T running wastegate pressure.
all have done the same thing it boosts fine untill the car has been driving 5-10 mins then it hesitates really bad or just cuts out at around 3500 rpm cheerz,james |

Is the factory MAP sensor still plumbed in properly? (along with the pressure exchange solenoid)
Is the stock boost solenoid still plugged in electricly? It sound like the typical Rs Lib limp mode.
