R34 Turbo issue Help please!

[TaylorS]

Hey guys i just recently got my r34 manual converted. since i have had it back it has been running slugish (worse then my NA r34).
so while driving it the boost gauge goes up in boost and you can hear the turbo spooling but it feels like i am not getting any boost at all! 
the part that seems weird is that it seemed to drive normal when cold? (felt like it had boost. i didnt test that to ghard though since the car was cold)
any help would be much appreciated, thank you

Is the car tuned or stock?

I’d be checking the timing or having a look at the knock sensors. 

Recently filled up with fuel? Could be a bad batch. 

Also check the coolant temp sensor.

Hey mate. Everything is stock expect the exhaust with is a hks.

No cant be fuel, i havent filled up since the conversion and it was running great before when auto.

Does it matter that its still running auto ecu?

Ok thanks i will have a look at those sensors, is there a way to test them?

Auto ecu shouldnt matter

I would check by plugging a computer into the consult port, there might be a way to check with a multimeter, maybe look up the service manual. 

Only other things i can think of are check for boost leaks or a blocked cat converter.

Don't start new threads - it just wastes time.

Really a blocked cat can do that?

Ok thanks mate. I will have to find a diagnostic tool with the consult end or take it to a shop.
