R-Tech VNT sticky turbo vanes repair

In 90% of cases this will stop overboost limp mode, return better MPG and make the car more responsive and safe.

Is this really that common that it will sort out limp for all of us that have limp and poor mpg?

The main question is how much is it to get done and how long would you need the car for?

Anyone used these guys for this work in the past? I know you guys have all been mapped by r-tech but anyone specificially had this work done as it seems like a tricky job. Anyone give any feedback about this job?

Is the Innotec not any good anymore then? I read loads over the summer about the Innotec service you guys provided which was supposed to be really good for £90 including the Innotec kit.

Variable nozzle turbocharger? I think.

Basically it has adjustable vanes in the turbine housing to redirect exhaust gasses to improve spool up, and reduce lag

For someone that has possible VNT sticky vanes what is the best advise on how to drive with it whilst you don;t have funds to get it fixed?
Can you do any damage to the car whilst driving with sticky vanes?

Yes, the turbo is working at 150% or flat out maybe seeing upto 40psi , so turbo seal will fail, can split intercoolers, boost controller working overtime trying to bring the boost down, poor MPG,  too much cylinder compression head gasket fail.
