Tuning fail?

[V6VTHolden]

Hi guys quick question. I got a mafless tune today with OTR CAI only other mod is 2 1/2" catback exhaust. 347rwhp. But I just realised I was running 95 fuel when I always use 98. Will changing back to 98 affect the tune at all?
The car is ss manual

wont affect the tune at all just depending on how far they went with the timing it will be safer with the 98, its prob good to have a bit of leway in it because if it sits around the octane will decrease slowly anyway so then it will still be fine...
