    Ported TB - Fuel Economy Drop

    I just put on a ported TB on my L98 6 litre.

    Improved throttle responce. Idle and drivability with my cam, but the fuel ecconomy has gotten worse by almost 2litres/100kms.

    Any ideas on how to get it back? nothings changed except the ported tb.

    Also would a hybrid openloop at low rpm / closed loop at higher rpm setup as mentioned in the other threads for the gen 3 work on the gen 4 pcm?
