Could be your in need of a grounding kit or it could be you have a hose off in the engine bay, check the vacuum lines to the plenum and the air intake(s)
Or it could be something else and as its new, chuck it at the dealer to sort... it dosnt sound right!
I saw one for a HR yesterday when I was looking around the web... thought you were still looking... should have book marked it! Just wading through my History now!
Nah, its a real carbon wrap, I got a guy in the states to do it for me and then ship it over. If you take the TK badge off its all plain, no holes!
Take a look at the RSW ones for a cover, fittment is pretty much spot on...
I only did the boot space, those bits were quite easy... I stopped at the bit on the top of the speakers!!
If I am going to get he rest done it will be by a pro!! Next will be the main centre console... think it goes well with the carbon....
