Going to leave it stock for a couple of weeks just to make sure.
BTW... I was on the "ract tune" since I got the tuner until now. I'll have to say its not a tune you want to keep on there for just around town driving. Shifts are pretty darn hard. I like it that way... but definately not a long term tune to leave on. |
The code dissapeared because the handheld clears all dtcs after the write. If it threw that code, it will come back. It is something that isnt a tune related thing.. Meaning no change to the software would make that show up. It will come back, It will just have to fail its 2 tests again. It "MAY" already be showing as a pending dtc in the software. It just has to see 2 failures before it will show again....
Could you tell a big difference in power/and trans going back to stock??
