I`ll forego the qualifiers. We are adults here. Self tuned w/ VT and the car runs really great, makes tons of power, and has so far been reliable as I could have asked since built motor. One odd thing it does, and I can`t recall when it started, is it seems to stutter or hesitate if I just mat it. Not a misfire type situation at all, rather it starts to accelerate, hesitates, then rips my face off like it`s supposed to. Almost feels like it`s caught in the CL/OL transition. Nothing particularly noteworthy in the logs. The tune isn`t specifically aggressive as far as timing goes. It seems to only do it at lower engine speeds (lower being 2500-3K)...if I floor it at 4K in 4th, for instance, it just hauls ass but if I`m in 2nd or 3rd and I`m scooting away from a stop sign it`ll do it. I`ll dig into it once the weather warms up and eventually figure it out but anyone have any ideas to cut my troubleshooting time down?
