2005 DTE STAGE I & II PCM PERF. UPGRADES COMPLETE
We have now completed our Stage I & II PCM performance upgrades for the 2005 model-year Cadillac CTS-V and they are available as of this writing. These two upgrades implement the same performance enhancements/improvements to the vehicle as our popular 2004 version does, so now DTE covers both current model years thus far.
All of the improvements/enhancements for either Stage or model year can be seen here in detail.
Happy motoring gents!
