Hard to tell as it doesn't look like any of the runs are a full throttle run...

Do it again at full throttle until redline if you can

thats about as high as i get without loosing boost :(, arnt the numbers low tho.
 done another log but again couldnt get past 6000 rpm, also logged my timing.
changed my n75 for an old c type i had lying around so logs are with the old valve in, how do the n75 numbers look.

can you check your throttle angle mate?

Agreed it looks like it's taking an age to get anywhere, N75 seems to drop off too

its 1.3* , i think this is within range, gotta new MAF coming, (doesnt go wrong if its not that, think the one thats in just now is over a year old so not bad  :grin:,) if that dont fix it,  then its N75 time, whats ppls thoughts on the H version, hit n miss ?, failing that ill be looking at the wastegate actuator, fingers crossed it aint that cos that would mean dropping the turbo to change it :(

You don't need to take the turbo right out for that :wink:

If I take the take the car out for a spin I'll get some logs for you have a look through for reference. Might even have one on the computer....

that would be great if you could m8 thanks, can you change the actuator without having to remove the manifold, heard its a right coont.

manifold has to come off unfortunately

These might help, they're old but might be good for a comparison







I think they were all from the same run...

starting to think its defo  more a weak actuator or n75 now tbh after reading up a bit on it, my boost gauge shows me peaking at 10 psi and then dropping suddenly, surely this would be the n75 not being able to hold the wastegate shut at that pressure and just opening.
