Re: anyone ever turbo an XLR
As said the 07+ XLR can be tuned with HPTuners or EFI live among others. The 04-06 cars have a different PCM that is not supported by any of the consumer-level tuning suites. That's why it is a lot easier.
A turbo XLR would be sweet. I'd like to see somebody do it. I'll lend whatever I can if someone does it.
