Guys, I've started to have just a bit more than a passing interest in WMI due to still owning the C230K. I only know one person using the system on their car, power wise it's 2.5 times my own and no expense spared either on all engine components, which is in a totally different league to my bus so to a certain extent the WMI benefits would not be comparable even if the principles are the exactly same. After doing some basic research along with the little bit of knowledge I already had (dangerous) I'm coming to the conclusion it's all positives to installing a system. So, has anybody been down this path, got some first hand experience or even knows about the system? Cheers in advance.
