Been thinking and talking with Justin about the idle issue, cams and long tubes. Piecing together bits and pieces I'm picking up along the way, my situation is thus-
I hate the idle/ low speed issues even though Justin has tuned most of it out. It's ok with the AC off but turn it on and the car won't idle. Parking lots are brutal to navigate. I'm also seeing incredibly high IAT readings even though it's winter. Come summer I won't be able to drive it.
Hot Rod cams have a shorter, more abrupt exhaust duration which seems to me would reduce flow. Justin said exhaust gasses were backing up into the intake which would explain the brutal IAT readings and idle issues.
In order to get the exhaust moving, I'm picking up some JBA headers. If that isn't enough then I'll replace the Hot Rod cams with something else. I'm growing to hate the cams in combination with my high flow heads. Just too much like a race car and not street friendly enough for me. I'm sure when paired with stock heads they would be cool. If the headers don't help then the cams will be gone.
