I have an 07 LBZ with a Predator/Juice *** stack, turbo back exhaust and trans go. I mainly use the edge on levels 1-3 for the guages and I leave the Predator on L3 and it works really well. I am fine with the power but I want to look at a turbo to lower the Egts while towing my sled trailer over the steep passes. I have seen what people posted on the GT40 and that looks great but I was wondering if there is a Turbo that will work well with my existing tune(s) and trans. I see that PPE and EFiLive have big tunes for the aftermarket chargers but I really don't want to add guages other than the edge. I take long sled trips to Revelstoke and I drive fairly fast to get there and need to keep the temps down when doing 80-85 over a pass. I have plenty of power now for that but the EGts make me slow down. Taking out the cat helped but I know the aftermarket chargers will help a lot more. Let me know. Thanks
