I went with the VECII. I purposely went with a set-up that shouldn't require an AEM as I had many quality and tuning issues with my previous car that ran an AEM, plus you won't pass emissions with an AEM as you ECU. The SCT should work out great for you. I would have gone that route, but the SCT was early in its development when I did my build. I am seriously considering going to an SCT, so I can get my closed loop driveability improved.
