How to tell if my cars been tuned

[TAILS83]

Just wondering if there is any way to tell if my car has been tuned before.

It's a vz ss. When I bought it it had a full exhaust system on it with stock intake and goes great.

No stickers on it anywhere to say it's been to a tuner.

Cheers.

If it's running mafless then that's a guaranteed yes.

If it has a maf, then I suspect no as most places tune would go mafless.

Only way to be certain would be to check the software. Not sure if your setup would do this.

Plus I am not sure how you actually tell if the tune is stock or not.

If you really need to know, get a tuning place to check. It would take about 5min.
