Hello everyone, I hope you all had a great christmas!
I've been messing around installing a slightly bigger Hybrid Turbo onto my Discovery TD5, I am looking for some help in what happens when it goes into overboost? As far as I know they're programmed to go into it at 20psi, right? My new Turbo came with the actuator preset to where it was supposed to be, however there was no power, I know there will be lag with a bigger Turbo on the stock map but there was nothing all the way through the revs, so I shortened the rod.
Now I have boost, not as much as the old Turbo seemed to have but it's much better. However, in 5th, on full throttle while climbing up to 70mph and I assume on full bost it judders at around 60mph, then has very little power. Once slowed down and stopped, it then has the full power again. I've checked everything uner the bonnet, so I'm wondering if that's overboost? I know it will need a map to run correctly with that Turbo, but is overboost what I'm dealing with most likely?
Nothing seems to be wrong under the bonnet.
Cheers!
