Just as you said. Stop pulling. This pulls hard to 5800. Yea sport mode on as always, yea junk stock rubber, but not loosing traction at 90 in 3rd. I just had that clip. Pulls hard at whatever temp.What do you mean goes “flat” ? If you’re reffering to the power flatlining up over 5, I understand. Mine pulls hard untill about 4800 or 5000 and it DOES stop pulling . Maybe not first or second, but its also warmer here in California and its harder to lose traction. Looks like pretty cold climate where you are at, and you have traction off? Are you on stock tires?
