not only does it give you lower IAT's, with meth you can also pull timing like you would with race gas. Its like getting the effects of race gas on pump. Vast performance sells a kit for the S4, i think its based of of the "DEVILS OWN" kit..

I know some people do it but w/m on stock turbos never really appealed to me, iv always felt if you arent happy with stage 2+, just go stage 3.....

 

I think the term ,is you can add timing, not pull timing.
