I was missing shifts when using the stick.

I haven't missed any shifts this week, and I've been driving it really hard this week. I wonder if the car needed to learn the new part? As stupid as that might sound, I know in the past my Z needed to learn the modded intake. It would stall between 2nd and 3rd gear, did it about 5 or 6 times in the week I put it on. After that the car never had another issue again, and that was for nine years!

@ Mingofish Good to know about the RR tune not being noticed by the dealership. That was kind of my hesitation, so maybe I'll look into doing it here soon.

Now on to find what's the tapping noise coming from my front left fendor. Kind of sounds like the front left brace is loose, or the shock has a loose bolt or something. I heard it yesterday when I had no music playing, and the windows down to hear the exhaust. Happens only over bumps.

Cheers,
