Hey Bforte. Pics uploaded (sorry about the size). Do you get a hesitation when you punch the accel. quick 5-6 times rapidly when just idleing. I have no codes runs smooth Gradual accel. no problems. Might be normal. Mine is sluggish from a stop too. I have about the same money into mine, mostly mods, air bag, bluetooth, freakin $55 cruise retrofit kit, 75$ aux cable. +1 on corners eh. Just amazing how well it handles even w/o sport suspension. They go good too, had mine up to 170kmh no vibration or rattles, could put a cup of water on dash wouldn't even spill a drop.
I use the touchless carwash every week, try to touch it as little as possible. Spent 2 days last yr removing swirls and then polish,wax. (HATE BLACK) Looks good clean though.
