HELP, waay to rich after turbo upgrade... midmount vector.

[stsubaru]

hi.
i have a 05 mcx turbo vector with a midmounted turbo.
after i changed from the mcx td04 16T to a garrett gt2860rs the sled runs waay to rich..
never under lamba value 11! (runs leaner on idle)
it bearely runs when the boost comes...
it ran perfekt until i changed turbo.

mod list:
midmount header.
msd 2225 fuelpump
mcx malpassi fuelpressure regulator
mcx intercooler
wiseco pistons 9.5:1 Compression
carillo h-profile rods
garrett gt2860rs

i guess its a carburettor problem??

i know this isn't going to help with your problem at all but where did you find the turbo for your sled i have an 05 rs vector and i cant find a turbo anywhere for it

Check for boost leaks. If it's building boost but not getting into the carbs the regulator will still add the extra fuel.
making it rich. Also check your fuel pressure. The regulator might have taken a dump on you.
