I have one vote on the PPE Garrett GT40R, tows excellent, and pairs very well with dual Fuelers. It spools fast and eveny, with no sudden surges. I love mine too.
I would have to say that the PPE GT40R kit has really worked out. I have been testing it in different conditions for months. This is definetly not a girlie charger, and is definetly comperable to the aurora 2000 and 3000 and one step ahead of the BD kit. Max boost with the dual fueler kit on it...
