Haven't seen that colour yet and probably we won't lol... Holden, for some reason, seems to get the better half of GM typically. I'll need to check on the build your Cruze part of GM to see if there is that option, I never though to check!
Did you paint your engine bay or did it come colour matched?
Wheels and suspension will be next. I like go and show, so I am looking into boosting the turbo up and adjusting the fuel to match.
I can tell you, there is an expert GM tuner who lives not very far from me... He is WELL known in the GM/Chevy market called Trifecta Performance... he doesn't have anything ready yet but he will be picking up a Cruze shortly to play with and he should have tuning ready for it shortly with mail out kits where you do data logs & tune until complete then you send tuning kit back (unless you want to purchase it)
