Had the alignment all setup properly for it, understand its going to be a handful thats why I love driving it as makes my evo feel slow and boring. The boost comes in as smoothly as my mapper could get it to its not so much that its when im flat at about 5/6k in 3rd and 4th Maybe ive done all I can and just have to put up with it on the road its mainly a track car anyway so handles completely different on full slicks.
