I'm running new tune as well. Much smoother acceleration particularly in low rpm.


Strange thing though after the tune I threw a P0304 code which is a misfire on number 4 cylinder. During install the shop had a P0404 code which is diff but same cylinder I suppose.

I can't get to shop until Monday but will have them check coil and plug.

Vehicle doesn't appear to be running rough or anything. I'm also curious why the former tune sort of suppressed this issue if in fact it's not a glitch.

If the light was not on I wouldnt know if anything is wrong. Seems to run fine otherwise.
