Hi,
I agree fit the above parts apart from the headers , totally waste of time I feel the stock headers work very very well we find especially when going S/C'ed , but we would supply a tuner S/C kit , this comes without any management or fuelling additions.
We then fit a return fuel system uprated pump , modify the fuel pump cradle , fit some Larger flowing injectors and remap the stock ECU. Worls so much better than the way HKS try to tune the fuel/igntion system.
If you email me at mark@abbeymotorsport.co.uk I will send you a quote.
