I am currently Stage 1 with it and no DP.
This will not be the case come Friday
However, with the time being as I am Stg1 with the intake, I'm not sure if it makes all that much a difference that I can notice. I mean 5hp or so isn't going to be noticable in the long run. The sound, for sure. The powa, not so much.
Like I've always said and maintain, Intakes are practically a waste of $$$, however as I couldn't get my Stg2 upgrade without it, I ended up buying one and made the choice to go with IE based off all the glowing reviews. I'm not disappointed in that aspect. :thumbup:
