Go ahead and chuckle at my little 3.0L. It reminds me of the story of the young sailor who hired a lady of the evening in a far away port. When she saw him undress she asked "who do you think your going to please with that!" "Me!" he replied with a big smile...
I got a deal I couldn't refuse on this CTS4 Thunder Gray Cromaflair. I tinted the windows, blacked out rims with red caliper covers. Reading this forum I purchased the RX catchcan and clean-side seperator. Couldn't resist a CAI and found CTSV mufflers so it can breathe. I figured I'd come this far so I went with the throttle controller, as well as KPE engine & trans tune. And, I'm still into it waay under the value of the car (2013 with 2K miles).
I'll never race anyone, I use it as my daily driver- yet everytime I look at it I smile, every time I drive it, it is a dream come true. I sold my late-model Mustang and I'm not looking back.
If I do ever dyno it, I'll post numbers- but as we all know, it will not ever be a 3.6L (and that is fine with me).
