I went Stage 1, Stage 2 is nice but I've heard its not the greatest on the dyno as far as the numbers it puts out... but the power band on the street is nice. This is what I've heard and read. Stage 3 is oh so great but I can't afford it... but if I could I would get it. Regardless you want to tune an SRT-4 to get more power out of it since they do run rich. I'm pegging 10.0 on my Wideband.
I just have the blue plate, I don't want any aftermarket bov at this time. I don't gain anything from it.
