It was and still is broken, but I will get it fixed/bodged.

Its currently running 1 bar across the rev range, but if I get my electronics right I'll soon have 1bar to 4500rpm then 1.3 til the redline. Then its remap time and more boost til I can afford a single turbo conversion.





It should run 280 as standard and 320/330 with a remap, but 350 is the very limit for the TT without silly money spent on it. People bang on about the lac of lag, but comparing mine with Jays, he's making more power than mine earlier in the rev range, so a single conversion is a no brainer now. I just need a smashed bug eye to cannibalise.

Running rich to Paul.

is that boost graph with boost controller

No thats how it was before the controller.

Its running rich because its missing loads of boost.

looks like solenoid not doin anything on high just using actuator spring is there a restrictor pill in boost pipe like the imprezas have

There is but basically one solenoid controls both boost levels. There is only one wastegate on the small turbo, that controls boost for both.

To be honest I've given up chasing the problem, I've tried all sorts and read just about every post on the internet about them. I could get to the bottom of it by changing the DPS sensor, boost solenoid, vac pills, dump valve, EGV...the list goes on. Even a leaky manifold can casue this kind of issue.

Slapping a boost controller on fixed the levels @ 1bar ish and its much better, but not right. I can set the boost controller to switch to high boost when the second turbo comes in and get my full 1.3 bar. I'm just fed up of the unreliability of the whole TT system. There are soooo many people running low boost levels on GTBs.
