We have a 1.6l TD in our Kick with 32x10.50 Procomp All terrains and it does just fine... At about 65-70 it is pulling close to 3000rpm, but seems all right and get 30+ mpg. So with 33s you should be all right. As far as power, it had plenty not doggy. But since we have turned up the boost and added an intercooler and it pulls pretty well. The instant torque is great!
