Here's the scenario: My cousin in So-cal has an wickedly fast Abt tuned S4 that has put down 260ish awhp and is a serious beast on the street and on the highway, especially highway. I have a Vishnu tuned stage 1 equivalence(ecutek-samco ic hoses,pulley,turboxs stealthback to scoobysport muffler, and jdm uppipe. We were at a light twice. 1st time we both feathered it out of first and went at it. I put about 1 car on him through the end of second. I slow down to a stoplight on the right and he pulls up to the left with a face like this Then he starts to build revs up, and i do too. However, we are on a small incline, and I think my launch is gonna bog. Light turns and he bogs but chirps with half a car length on me. I bog hard but recover quickly(probably super fast spool of VS1) and start ripping on him end the end of first. Second, I pull about 2 cars and maintain to almost the end of third where we shut it down bfore jail time speeds. He pulls next to me with the WTF face and remarks coming out of his mouth. I am trippin, because I thought I was gonna get owned. Maybe it's the 6-7 hundred pound difference. I am just stoked, cuz his car is fast as "$#@&". We've pulled easily on stock C4s in his car. HOw come our cars don't have that "fast feeling" if you know what I'm saying? I think it is super smoothness of the Ecutek and Shiv's tuning.
