Power loss in high RPM

[tayl51601]

I dont know if anyone can help with this, i havent had much luck yet.........

I recently got my clutch changed and ever since my car looses power after about 5,000rpm. It almost feels as though something is slipping or something is restricting the power (like the ECU).........

Im running an avo turbo with handata s100, i got it tuned a while ago and everything was sweet until the clutch change.

My motor is a b16a2, i know its not the clutch slipping as i have 135kw and running a cushion button clutch as well as i have tested the clutch and it bites hard.

Does anyone have an idea what could be causing the power loss??
Could it possibly something to do with the flywheel or gearbox?

Im hoping it might just be that i need to get a re-tune done.
Im taking the car in next week but the tuners dont know what might be the problem and i was wanting to try find something out before it goes in to make the whole thing a lot easier................

Any help would be appriciated!!!

recheck all the vacuum lines

go and get a smoke test it will show if there is a leak in your pipes ....

I found out last night its the clutch...........
When i tested it i was dropping the clutch when changing gears and it was biting hard but i think thats because the plates hit each other hard and gripped but when just sitting there they are not forced together hard enough.

I think you can adjust this with the hydraulic or something??

Does this sound right? If it is, is it easy to adjust or do i need to drop the gear box again???

did you bleed it?

I didnt change the clutch, i got a mechanic to do it.
Would they have bled it as apart of changing the clutch??

Check the pedal height & free play.
Could be out of wack & constantly pushing.
