I will be Dynoing my GSR next week wit AEM SRI, Apexi N1 cat-back, Car sound 2.5 high flow, DC JDM ITR 4-1 Header and Apexi V-AFC2. Back in september with just SRI and Cat back i put down 161whp. Now im looking to put down 170+ with this basic set up now. I was wondering what other minimum mod I can get between now then next week that will help out a little on the Dyno, FPR?.
