RE: I need your opinion
Not exactly. It would only be a problem if it caused the engine to overheat dramatically. Proper tuning should keep that from happening. I would expect that the engine temps would be higer than if it were run on a cooler day. I read someplace that a good rule of thumb for engine temps is around 160 - 180 degrees above the ambiant temps.
Having said that I DO NOT reccomend tuning for temps. Tune the engine for sound, smoke and performance and then check the temp for a reference point.
