No its not the n75 they have been playing with. Basicly revo suggested the forge actuator wasnt a good idea!
Yeah basicly my revo settings couldnt handle the tweaking. I think, wasnt 100% as it was second hand info

what are these turbos supposed to handle? as my old turbo on my derv was designed to hold 2.2bar peak................. and around 1.9 bar at redline.
surely they could hold more than 1.3 bar at the redline?

What i mean is that your not going to be able to control the boost spike with the N75 controlling the boost! It's simply too slow to react especially if you have replaced the F valve for a H or J.
Diesels boost more anyway! The guy who puts them together said that it could hold 1.4BAR @ the redline. But we have been struggling to get 1.3 BAR
That's right, and Scotty has a turbo that WANTS to make more boost, but it's run on standard settings - so no wonder it's surging...
It might be possible to speed the N75 up by adjusting it, but that would make the surging worse, you could reduce the surging but that would reduce peak boost and probably make the spiking more erratic. You can't have both.
You either need to get it mapped to suit (and reduce the requested boost lower down
) or turn the boost up and get a manual boost controller. IMHO.

oh right............... could you not fit a tdi hybrid with the K04 fitment manifold then? that way still standard fitment but able to withstand more boost?
Sie's running what a few TT owners run:

A couple of different ways to plumb one in though, Sie would have to tell you how his is.
Apexi AVC R looks like a nice bit of kit, but not "cheap". There's a few people run them - I think Robdon and Bill have them and some of the beeza boys?

Yup, i know my turbo blew to pieces after a short 5-10 min blast on full chat as the egt were up to narly 700 degrees
looks a nice piece of kit, has it sorted SIE's spiking issues.
700 degrees is normal for egt's.
No! Like i said it needs additional control the N75 isn't sufficent. Only way i can think is to use a PD150 map sensor so the ECU can see it then map it to suit.
Yeah MBC is the way forward i think. I had intended on getting a jabba re map with fun twister but they didnt want to map the turbo.
Ive looked at the apexi unit but its a bit expensive, any one know of any other good alternatives?

Sounds jut the bit of kit i need really (just looks very back yard modding tho, looks like something off a radiator control system!)
Sie do you have an pics of yours installed?
