OEM wgs working properly cannot boost past 1.2 if that...

Hey Mark. So what was determined to be the cause of his issues? The tune?

I'd appreciate any pointers.

Thanks guys.

Try this, it's the cheapest fix of all and worked for me when I had an overboost after swapping intercoolers and having a leak in one of the hoses. Disconnect the battery for about 20 min, reconnect and go drive it so the ecu can readapt.

I hope that was the culprit. Left the original N75 in for now, reconnected the hose and disconnected the battery. We'll see in a few days if this fixes it. Thanks, everyone, for all the tips so far.

Weird...Eurocharged said my ECU looked like it had a stock tune file and confirmed this to be the case with a local Porsche dealer. Getting my ECU back hopefully this week with the EC tune, but still puzzled about how the GIAC tune disappeared.

No, EC is moving the support for my E55 tune over to the 996. I wouldn't have considered a new tune if it was going to cost me $$.

Originally from Chicago, but based out of Houston now. They've had Porsche files for a while now. They also do the tuning for Underground Racing's turbo Lambos.

Not sure of this has been said. But you you do not want to boost your turbos or egine that high. You will run out of fuel, or damage your turbos. Get the mechanical prblem professionally fixed. This is not a tune issue.
