It still seems so wierd to me that a bit bigger of a turbo at 5psi would use have more issues than a vf-11 at 7-8 psi. i never had any fuel cut issues with it!
Oh, and subaruimprezapower, i didnt have any check engine light from boost until it accidentaly spiked to about 10 psi on my little turbo. with less than that, you shouldnt get any codes at all.
Walbro 255- yes
Stock injectors- yes
Boost- 7 psi
Upgraded injectors isn't usually needed at these boost levels and won't run properly without some sort of electronic fuel/engine management. vf-11 should be spooling sooner because of the smaller turbines fyi.
Keep the td04, upgrade fuel pump, buy td04, enjoy being faster
This should help you out and should get you out of requiring a wideband. http://www.rs25.com/forums/f7/t10779...arts-list.html
