So I had my motordyne m370 and stillen g3 installed and got an uprev dyno tune maybe a month ago.

Ever since then I noticed a weird "popping" noise at low rpm's as I am taking off or just lightly pressing the throttle. Sometimes it even just makes the noise constantly while idling, but only rarely. I was at a muffler shop for something else and asked the guy and he said I had an intake leak, possibly a vacuum hose.

I'm gonna go to a regular mechanic (not the shop that installed and tuned) to take a look at it but my question is if my car was dyno tuned when it had the leak, will I need to have it tuned all over again once it is fixed?
