i just installed my Vf34,fuel pump,injectors. and im getting some knock! im running the base stage 4 map on my uteck and was getting about 18psi so i closed the abc and now im getting about 15.5psi but i still get knock. im about 5000 feet up and only get 91 octane gas, so what can i do to get ride of the knock,maybe octane boost or colder plugs? i cant do any tuning on the map because my laptop took a crap on me and i don't have money for a new 1.
also i will be installing a FMIC as soon as the where gets nice here!
any help would be nice!
