It is good to hear that
It is good to hear that Cadillac allows tuning. As long as the engine can handle the extra boost, turbos are often easily tweaked to make serious power. Cadillac got so much right with the CTS-V and ATS-V, that it is a real shame that they are dropping them both. Unfortunately history has shown that GM regularly axes their models just at the point when they have worked out the bugs. Enjoy your CTS-V!!
