Been driving with the bluespark for a while now. Has made a huge difference, then added a pierburg valve in the wg side and it's just all around better and more consistent. Honestly traction is my biggest issue at this point. With my lightweight wheels I cannot floor it anymore and not spin the tires even in 2nd gear... so once these burn off I will be looking for some better rubber.
