Turbo failure after ECU tune

If you have a great memory, you may remember this Bentley GT Speed from a while back. We treated it with an exhaust setup over utilizing a custom secondary cat delete and X pipe. From there we topped it off with an EVOMSit ECU remap. Well, apparently all that extra power didn’t come without a price, as 6 months later it returned with boost pressure faults in the ECU. P0234 would set and put the Bentley into limp, or failsafe mode.

This makes me worried about getting an ECU tune. How common or likely is this issue?

We do an average of 1-2 Bentley flashes a month, and have been for years. I recently heard of one car that had a faulty bypass valve (the spring rusted and broke?) that was repairable with our Billet BRV kit, and this would be the first wastegate failure I've ever heard of. Those are the only two vehicle issues I've ever been aware of with these related to performance, and I think it's questionable if either issue was related to being tuned or not since it was odd issues like oil causing the wastegate to fail, or water getting into the turbo causing that spring to rust.

I wouldn't worry about cars with just a tune. Yes any time you perform modifications you up the probability of having issues but a tune has relatively low chance of component failure. When I worked at the dealer we had a valve spring failure on a flying spur speed with less then 50 miles on it. We replaced the engine basically during the PDI procedure. Sometimes stuff happens
