Hey guys, I have the greddy kit and I wanted to know If I were to retard my timing would I be able to boost more? I'm on the stock wastegate and I have tightened it and it spikes up to 8-9 psi however I dont let it go past 5-6 psi. Anyway I can safely boost the 8-9 psi without getting EMANAGE ? I'm on stock 1.6 injectors. Should I get the 1.8 injectors and retard my timing ? A couple of my friends who mod their cars religiously say that it is a good idea. Any help would be appreciated. Oh and btw only reason why I have it tightened is because there is MUCH less boost lag. I hit over 6 psi by 4K.
