I don't do many mods but I may replace my cats with test pipes this spring. I will have it done in the same place that tunes my car. So after having them install the test pipes, I'll have them put the car on the dyno & tune it.

I BELIEVE? that mod will make my car run leaner. Running lean is not such a good thing for the engine. So the tune will make my car run safer, better & they at the same time will make sure the car has no lights or develops any inspection issues later on.

The dyno pull will show where & how the power curve looks & we can adjust/choose the shifting & redline points.

So while I'm there for the test pipes installation..............
