No. The tune was the most recent thing I've done.
I did the HKS exhaust in February.
I did the Stillen intake in March.
I did GTM Resonated Test Pipes in April. (I put on 7000 miles with these installed too!)
Then I switched them out for Motordyne Art pipes July/August.
And finally got an UpRev tune a few weeks ago.
My Z has never had issues. The SES light did come on about about 480miles after installing the ART pipes but I was literally driving to the other coast to get tuned.
