I also went with a high flow by Precision(same as Daleo) but went with an SS1. For me I was after nice low down responsive power. It is still slightly lagier then stock. But hardly noticable. But the power delivery and increased high end power is very noticable. I will shortly be installing 1000cc injectors a bigger fuel pump and an Adaptronic ECU along with a couple more bits and pieces, At which time i will upload results for everyone to see. My goal is to have very minimal lag.
