After doing some research I'm leaning towards the HPF FMIC but I'm hanging out for the matching HPF charge pipe they hope to release by December. Anyways, I've noticed you have the HPF FMIC so what are your honest thoughts on it? What power gains, if any did you notice? Is it a noticeable pull, like adding a tune? What were your mods before you put the FMIC on and what were your before and after temps? If you could do it all over again would you choose the HPF? My main reason for doing this mod is to keep the temps down in my car because 104+ degrees F here all the time throughout summer and I don't want to think twice about putting my foot down. I also plan to remove the plastic grill so it's on display too.
