Terrible surge at hard throttle
i have an 02 lb7 i have added an a cold air, edge attitude, 4 in turbo back, the injectors were replaced about a year ago. The problem i am having is at at a hard throttle it surges something fierce i have noticed a surge at idle is all this a regulator problem and should i also install a lift pump so not to starve the pump of fuel? just looking for a point in the right direction


You will get a much better response to your question if you ask it here:
Chevy/GMC Duramax 01-04 LB7 - Diesel Bombers
Unfortunately I do not know enough about the LB7 to be of any assistance.
Good luck though!
