engine bogggg hello
i just sigined on to this cite and i'am in need of some help. i have just built a 408 ls1 stroker with a lingenfelter cam, port matched heads,and a vortech t-trim charger with icebox cooler and i converted the tranny over to a 4l80e.
i brought the truck to get tuned at a dyno shop and it seems that they cant figure out what is causing this bogg.
From a dead stop the truck has no power it sputters and falls on its face. but if you are rolling at about 20-30km/h it launches hardddd and keeps going. i dont know whats causing this bogg down low. has anyone ever had this problem???. the fuel system has all been upgraded with a fuel pump , regulator, and injectors. the guys at the dyno shop are saying i need a fuel management system like (big stuff or mega squirt) is this true? i would really appriciate some help thanxx...i want my truck back...
