Get what i mean?

So im my case i knew there was some minor things i needed to do which i did like plugs, fuel filter, etc. And the car ran tons better.

And the other thing is, i cant really "rip" out with the car from a stop cause its only a 1.8T, heavy for its size, and AWD. Even with my chipped audi right now, you dont have the i guess torque at hand from a stop like i do from my pathfinder, where if i hit it to 2.5-3k RPM it rips and my tires squeel, while the audi takes a little longer to even get to those 2.5-3k RPM;s from a stop if you know what i mean.
