Hello all...

I have a tdv8 with 166k I'm hoping it's not the turbos but I'm having loss of power, no eml lights etc but I have a few codes that come up. Will post picture.

I drove the car one night went to pull off and all of a sudden no power. No smoke or anything still runs okay and drives but just no turbo power at all...

I'm getting more pressure going through one of the mafs then the other so is causing limp mode.

The body was removed last year at a cost of thousands to replace the ace pump and rear roll bar...

I don't want to have to get it removed again if its the turbos have gone! Any sort of help would be appreciated!

So few things to check here:
1. air flow/ pressure errors - check for intake leaks. common issue on the boost side would be cracked manifold, or one of boost pipes - from the intercooler to manifold, or one of entering the intercooler at the bottom. Also it is possible that there is some crack on the before-turbo part - like the PCV to intake connection. Check turbo actuators for sticking. Broken, or leaking EGR can be a culprit too.

2. Cylinder balance issue - check the live data balance, as there is some issue - missfiring can cause slight flow difference - disconnect IC to manifold pipes (and check them). then start engine (without the pipes, so it works as naturally aspirated), and check the air flow going out of IC, and also check the exhaust speed from both pipes (you can use some simple anemometer for better measurement, but probably just by hand you can feel if there is noticeable difference). Anyway the injector issue should be fixed - it's rather on the cause, than the symptom side.

3. Manifold tuning valve - there seem to be some electrical issue (the manifold is used to separate both sides of plenum manifold when required). The electric MTV is placed under the vacuum pump and it opens vacuum to the valve in the plenum manifold.
