Just installed a boost overlay in my dash cluster. Looks really good. Now I can see my guage go to up to 16 if my eyes can look at the guage and road at the same time. Ha. Plenty of wire for the two connectors but no vaccum hose lenght at all. I used a pair of finger clippers instead of dikes to snip the stud off the needle. It is tough to reconnect the hose back on but it can be done. Tight very tight. Or you can snip the hose and add lenght to it. I did not. I routed the hose under the bar and it gave me about 3 to 4 more inches without kinking the hose. Took me about an hour and a half. A couple of breaks and a beer or two.
