Booost,
maybe I can help.
My daytime phonenumber is 031/3212430.
I recognice Your screenname, something from
a mutual friend perhaps?...
But I don´t know about any turbolag on those
kits? I have also driven Erik´s bike, and
I can´t say that there were any lag to talk about. I have built my own turbobikes so I have comparisons.
Regards / Christer
